希望把原来的一个功能恢复

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Check out all the menus and keyboard shortcuts. Maybe the feature already exists?
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting to see if the feature already exists
• See if someone already suggested this under Issues or Discussions

Description

当我添加一个开始编辑点时，希望能自动把结束的一个编辑点加上，因为使用习惯原因，以为添加上开始编辑点，默认会有结束编辑点。导致我在导出的时候遗漏最后一个视频片段。
