Double-click to turn the taskbar on or off.

### Description of the new feature / enhancement

您好。

是否可以添加双击任务栏，打开【自动隐藏任务栏】时则关闭，关闭时则打开的功能。

Could you add a feature that, when double-clicking the taskbar, turns it off when "Auto-hide taskbar" is enabled, and turns it back on when it's disabled?

### Scenario when this would be used?

1.专注写文档时，想要桌面上更干净，需要任务一直隐藏。
2.收集需求或解答问题时，需要从各种文档和聊天工具中切换，就需要设置任务一直显示。

而这两种场景，有时一天要切换好几次。

1. When focusing on writing documents, keeping the desktop clean requires tasks to be hidden.

2. When gathering requirements or answering questions, switching between various documents and chat tools requires tasks to be always displayed.

Both of these scenarios sometimes require switching several times a day.

### Supporting information

_No response_

The issue names no files, tests, or entry points. First locate the PowerToys component responsible for taskbar behavior and determine how Windows exposes the Auto-hide taskbar setting. Done means double-clicking the taskbar reliably toggles that setting in both directions without affecting other taskbar behavior.
