I would like to request a feature that may be very useful for other people as well.
Would be great to have a hotkey or button in the Title Bar of windows to dock them to one of the sides (or top) where they will be hidden with just an indicator of their presence. Once we hover the mouse, click the indicator or press the hotkeys, the window would appear again. Then when the focus is changed to another window or the hotkey is pressed again, it would return to the hidden state.
This video explains better than I could try writing: https://www.youtube.com/watch?v=e0yLqr8mjsg
