Working with multiple windows can often become a tedious process. When you want to close all other windows that you don't want to work on, you have to search for the close button or right context menu entry to close the windows. It would be nice to have hotkeys to trigger the following commands that are similar to some browsers features:
Hotkey Function
WinKey + F2 close all but active window on taskbar
WinKey + F3 close all windows on taskbar
WinKey + F4 locked windows to prevent accidental closures on select windows
