Double-clicking a category icon returns you to its first page

[CaptRobau]

In a few programs, I can't remember which, double-clicking an icon returns you to its original state (first page, top of list, etc.). I've always found that very intuitive. I often want to go back to the first page of a category, especially with mods installed, so something like this would be very helpful have in KSP too.

I often find myself clicking the tab at the top to go to the first page and it takes me a moment to realise I was already on that tab.

I'm not sure double clicking is needed but I support the general idea.
