- HUD/search via global-menu - You could find any option in menus by typing them (https://www.omgubuntu.co.uk/2012/01/hud-new-unity-feature).
- Menus in the top bar (like KDE/macOS), but also in the title bar of application (quite unique approach - https://ubunlog.com/en/ubuntu-14-04-menus-in-the-title-bar/).
