My favourite gesture in Gnome is Super Key + Mouse Scroll to change the workspace. In keyboard shortcuts configuration I can see the option “Move window to next workspace” (Or something like that, my system is not in English) and It would be amazing to have the option to map that shortcut to, for example, Ctrl + Super Key + Mouse Wheel. This will improve the speed of workspaces workflow.
Implementing it this way, would let other users set up their own mouse + keyobard shortcuts. It will be cool to consider all mouse buttons (for those mouse that has side buttons).
Thank you for the amazing work on GNOME!
