[feature request] mini window/popup for task complete

[vfxturjo]

Hi, your software is amazing!

I want a feature: a small notification-like popup (for 0.5/1/any custom seconds) shown for action taken by GestureSign.

Example:
when i apply the copy gesture, on the right bottom of screen, a small pop up will be shown, saying "Action: Copy" or "hotkey: Ctrl+C" for 0.5 or 1 seconds and then disappear automatically.
