sessions are automatically hided[suggestion]

Dear Authors,

Like SecureCRT or MobaXterm, sessions can be automatically hided when the mouse moves to the sessions area, and hided when move away.

Now WindTerm need many steeps to display or hide and it takes up a lot of display space.

Thanks

No source file, test, or entry point is named. Start by locating the sessions area and the existing controls used to show or hide it; done means the area automatically hides when the pointer leaves and reappears when the pointer enters, while preserving access to sessions.
