I use Kickoff as an Application Launcher, we all know how it is made! There are all the categories, the part where all the installed applications are and as soon as you click on the icon or press the super button the Favorites appear, and it is precisely for the “Favorites” section that I got the idea of wanting it like the Gnome and Android Menu, that is, if you drag an APP icon over another it forms a group of APPs that can be renamed as you want, in my opinion an approach like this improves productivity, if you do this you will need a back and return button to navigate between the created groups.
