 ## Usage
 
 ### Importing Skeletons
 
-Use the **File** menu to select **Open** or **Batch Open** to import skeleton files.
+There are 3 ways to import skeleton files:
 
-### Adjusting Skeletons
+- **Drag & Drop/Paste:**  
+  Drag and drop or paste the skeleton file/directory into the model list.  
+  This method automatically searches through the provided files and subdirectories. Although convenient, it relies on the file structure and has its limitations.
+  
+  - Only standard files with `*.json`, `*.skel`, or `.atlas` extensions are automatically detected.
+  - The skeleton file and atlas file must have the same name.
+  - The version string in the skeleton file must not be modified.
 
-Select one or more items in the **Model List** to display adjustable parameters in the **Model Parameters** panel.
+- **Batch Open from the File Menu:**  
+  This method offers more file flexibility. You can drag and drop or paste files into the file selection dialog, and additional options are available.
+  
+  - The filename restrictions are similar to the above, but you can use the panel’s file selection button to choose skeleton files with non-standard extensions.
+  - You can set a fixed load version to handle cases where the version number has been modified.
 
-Right-clicking in the **Model List** allows you to add, delete, or adjust list items. You can also drag items with the left mouse button to rearrange them.
+- **Open a Single Model:**  
+  This method offers the highest degree of freedom, allowing you to select any skeleton file and atlas file without filename restrictions. You can also set the load version.
 
-### Adjusting the View
+### Adjusting Preview Content
 
-Mouse operations supported in the **Preview** window:
+The model list supports right-click menus and various shortcut keys, and you can select multiple models to adjust their parameters in bulk.
 
-- Left-click to drag the skeleton
-- Right-click to drag the view
-- Scroll wheel to zoom in/out
+In addition to the parameter panel, the preview area supports several mouse actions:
 
-Additionally, you can adjust export and preview parameters through the **View Parameters** panel.
+- **Left-click:** Select and drag models. Holding down the `Ctrl` key enables multi-selection, which syncs with the model list.
+- **Right-click:** Drag the overall canvas.
+- **Scroll wheel:** Zoom the view.
+- **Selective Rendering:** The preview area supports a mode to render only the selected models. In this mode, only the selected models are displayed, and selection changes must be made through the model list.
 
-In the **Functions** menu, you can reset and synchronize the animation time for all skeletons.
+In the function menu, you can reset and synchronize the animation time for all skeletons.
 
-### Exporting Animations
+### Exporting Preview Content
 
-Select **Export** from the **File** menu to export all loaded skeleton animations as PNG frame sequences, based on the current preview settings.
+Both preview images and videos can be exported.
 
-You can view the full duration of each animation in the **Model Parameters** of each skeleton.
+- **Preview Image:**  
+  The exported preview image shows the model in its default state, with one image per model.
+  
+- **Video (TODO: Currently only supports frame sequence export):**  
+  The complete animation duration for each skeleton can be viewed in the model parameters.
+  
+When the preview area is set to render only the selected models, the exported content will include only the models that are displayed.
+
+### Format & Version Conversion
+
+You can use the tools menu to convert skeleton files. This feature supports conversion between binary and text formats, as well as between different versions.
+
+Currently under development, it only supports converting `3.8.x` binary format to text format.

 ## 使用方法
 
 ### 骨骼导入
 
-**文件**菜单可以选择**打开**或者**批量打开**进行骨骼文件导入.
+有 3 种模式导入骨骼文件:
 
-### 骨骼调整
+- 拖放/粘贴需要导入的骨骼文件/目录到模型列表
 
-在**模型列表**中选择一项或多项, 将会在**模型参数**面板显示可供调节的参数.
+    这种方式会自动查找传入的文件列表以及目录内的子级文件列表, 虽然方便但是依赖模型文件结构, 限制最多.
 
-**模型列表**右键菜单可以对列表项进行增删调整, 也可以使用鼠标左键拖动调整顺序.
+    - 仅支持自动发现标准的 `*.json`/`*.skel`/`.atlas` 后缀文件.
+    - 骨骼文件和 atlas 文件需要是同名.
+    - 需要保证骨骼文件里的版本字符串不是魔改过的.
+- 从文件菜单里批量打开骨骼文件
 
-### 画面调整
+    这种方式提供一定程度的文件自由度, 文件选择框里同样支持拖放/粘贴, 但是多一些额外选项.
 
-**预览画面**支持的鼠标操作:
+    - 文件名限制条件与上面类似, 但是可以通过面板的选择文件按钮选择非标准后缀的骨骼文件.
+    - 可以设置固定加载版本, 便于应对魔改过的版本号.
+- 选择单个模型打开
 
-- 左键可以对骨骼进行拖动
-- 右键对画面进行拖动
-- 滚轮进行画面缩放
+    这种方式自由度最高, 允许选择任意的骨骼文件和 atlas 文件, 可以没有文件名限制, 并且也可以设置加载版本.
 
-除此之外, 也可以通过**画面参数**面板调节导出和预览时的画面参数.
+### 预览内容调整
 
-在**功能**菜单中, 可以重置同步所有骨骼动画时间.
+模型列表支持右键菜单以及部分快捷键, 并且可以多选进行模型参数的批量调整.
 
-### 动画导出
+预览画面除了使用面板进行参数设置外, 支持部分鼠标动作:
 
-**文件**菜单中选择**导出**可以将目前加载的所有骨骼动画按照预览时的画面进行PNG帧序列导出.
+- 左键可以选择和拖拽模型, 按下 `Ctrl` 键可以实现多选, 与左侧列表选择是联动的.
+- 右键对整体画面进行拖动.
+- 滚轮进行画面缩放.
+- 预览画面支持仅渲染选中, 在该模式下, 画面仅显示被选中的模型, 并且只能通过左侧列表改变选中状态.
 
-可以在每个骨骼的**模型参数**中查看动画完整时长.
+在功能菜单中, 可以重置同步所有骨骼动画时间.
+
+### 预览内容导出
+
+支持预览图和视频的导出.
+
+预览图导出的内容是模型的默认状态画面, 每个模型一张单独的预览图.
+
+视频(TODO: 目前仅支持帧序列导出), 可以在每个骨骼的模型参数中查看动画完整时长.
+
+当预览画面处于仅渲染选中状态时, 导出的内容仅包含被选中的模型, 也就是在画面中显示的内容.
+
+### 格式与版本转换
+
+可以通过工具菜单进行骨骼文件转换, 允许二进制和文本格式之间的转换, 以及不同版本间的转换.
+
+目前处于施工中, 仅支持转换 `3.8.x` 二进制到文本格式.

+    Microsoft ResX Schema
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
