in ubuntu the applications in the dock display with a number. If you continue holding the super key and then hit one of those numbers, the application launches…is this feature available in Manjaro Linux …?
Ubuntu proper uses GNOME as its graphical user interface, and GNOME is a very different beast to KDE Plasma.
If on the other hand you are talking about Kubuntu, then what is possible there should in theory also be possible in Manjaro’s implementation of Plasma. You may however need to install latte-dock ─ it’s in the repository ─ or perhaps another dock to be able to get that kind of functionality.
