Can the grouping function be optimized?

[Guyungy]

Feature Request 功能请求

1. 在设置内将订阅源分组是个困难的事情，能否优化分组功能，支持拖动订阅源以切换不同的分组（It is challenging to group subscription sources within the settings. Can the grouping function be optimized to support drag-and-drop functionality for switching between different groups?）

2. 当我点开文章之后，菜单总会消失，需要手动将菜单再次点出来，能否增加将订阅源固定功能（Whenever I open an article, the menu always disappears, and I have to manually bring it up again. Can you add a feature to pin the subscription sources menu?）
