Chains — ability to define multi-step actions for issuing using command palette, hotkeys, gestures, menus
Customizable controls:
Command palette (somewhat, in major groups only)
Menus, including context menus and main menus
keyboard shortcuts
including single-key hotkeys (which are a bit buggy for now and keep misfiring during address editing)
not including possibility for key sequences, unless done via menu system
mouse gestures
