Hello everyone!
The Sway community WM use nwg-drawer as an application launcher and I would like to add other Categories like a Waydroid category, for example.
I searched the Github but I still don’t understand where the categories or directories can be edited. 
It is in the apps desktop file:
[Desktop Entry]
Type=Application
Name=Run WR Script
Comment=Runs the WR Bash script located in your home directory.
Exec=/home/xircon/scripts/wr.sh
Terminal=true
Icon=utilities-terminal
Categories=Utility; <<<<<<<<<<<<<<<< here
Thanks for the input! I found the desktop directories “basic layout” on my system that corresponds to the files on the github at /usr/share/nwg-drawer/desktop-directories but they don’t match so i suppose that they are elsewhere. Probably on the /etc folder so i am still looking.
I also looked on another laptop with a endeavourOS lxqt wayland session and I have the same categories so i suppose that it could be actually just the categories from any EndavourOS session? anyways, I know I will find it eventually 
/usr/share/applications is the directory.
Actually the real problem is nwg-drawer, I changed a category from Utility to Banana, it still appears in Other 
Piotr must have hard coded the categories, if you type waydroid into the search, it does list all waydroid apps.
The waydroid desktops are in ~/.local/share/applications:

I also looked at both the Arch, Sway and freedesktop wiki about xdg menus and while there is mention how different DE handle them and where you could find those menus, it is vague and doesn’t mention anything if you use only a WM session like Sway.
Anyways, thanks for the effort, i appreciate it a lot. 
Oh and sorry if i make any typos or if I seem confused: I am almost finished working a 12 hours nighttime shift and I had a couple of things to handle at the same time. I guess that a good sleep will help me think of a solution or gave me the wisdom to call it quits.
