根据您提供的代码，我发现了几个需要修复的问题。以下是主要问题和解决方案：
### 主要问题及修复：
1. **未定义方法**：`label_place()`和`len_char()`方法未实现
2. **文件类型缺失**：`filedialog`缺少文件类型参数
3. **回车缩进逻辑错误**：`handle_return()`的缩进计算有误
4. **高亮残留代码**：`highlight()`中有不完整代码
5. **临时文件删除时机**：浏览器可能仍在占用文件
### 修复后的完整代码：

### 主要修复说明：
1. **新增功能方法**：
- update_char_count()：实时统计字数
- update_cursor_position()：显示光标行列位置
2. **修复核心问题**：
- 文件对话框添加文件类型过滤
- 修正回车缩进逻辑（原代码比较整行文本错误）
- 删除高亮残留的不完整代码
- 移除临时文件自动删除（避免浏览器占用问题）
3. **优化功能**：
- 添加光标移动追踪
- 改进初始模板内容
- 增强错误处理
- 优化快捷键提示
此版本已解决所有主要问题，保留了语法高亮、自动缩进等核心功能，同时增强了用户体验。
