Hello, thanks for all the work on the AppLink. I would like to make a suggestion that you change kmi = km.keymap_items.new('wm.call_menu', 'Q', 'PRESS') to kmi = km.keymap_items.new('wm.call_menu', 'Q', 'PRESS', shift=True), or something similar. That way the addon does not interfere with the default Q quick menu shortcut in 2.80.
Thanks again for all your hard work
