I just notice Marco has hidden shortcuts that are very hard to search and change.
I recently upgraded to 19.10 and switched to use Marco adaptive compositor, I noticed my custom shortcut to create new tab in Tilix is now overridden with opening new MATE Terminal window instead (Super+T). I searched everywhere for the config, in Keyboard shortcuts and in dconf configs, finally found it is deep in /org/mate/marco/global-keybindings/
Can we move these Marco keybindings out to the Keyboard Shortcut window in Control Center where it is easier to discover and modify?
