[jsfdez]

A mod that adds keyboard shortcut numbers (1-9, 0) to taskbar icons like 7+ Taskbar Numberer:

Well done! I wanted to create a mod like this, but didn't have the time to work on it.

Is it ready to be merged?

From a quick test, it looks like numbers aren't being updated right away after reordering. They only update later after doing additional operations such as switching to another window.

Another issue that I saw is that the running indicator sometimes becomes less visible, as if it moves behind the background layer:

I encountered this issue in the past, I saw that it happens when removing a child window. A possible workaround might be to never remove "WindhawkNumberOverlay" elements, and make them invisible instead. Then, when it's needed again, check if it's already there, and if so, make it visible and use it.

Also, when using the "Never combine" configuration, multiple buttons of the same app use the same Win+# shortcut, so the numbers are incorrect in this case, for example:

It is already working somewhat fine, thanks! I'm already using it! :)

Merged in #3610.
