OpenJDK tools should not be in menu of apps after installation
These are too low-level and shouldn't clutter this list.
Yeah even as a Java developer I don't think these belong in any menu. Though this may be more of an Arch issue and less of an omarchy one, since I think the application-launcher originates in the arch package.
I felt the same way, tried to remove it (I don't use java) but dependencies to snapper made me reconsider. I hid the files manually though by creating files that hide the entries from the "apps" menu:
create following files in .local/share/applications :
jconsole-java-openjdk.desktop jshell-java-openjdk.desktop
These files should contain these config settings:
[Desktop Entry] Name=Java 24 Console Comment=Java 24 Command Line Exec=java Icon=java Terminal=true Type=Application Categories=Development; Hidden=true
It worked for me, that it kept the jdk tools operational but de-clutterd the bar. I also created e.g "libreoffice-calc.desktop" to hide redundant entries in my menu
Important is to set Hidden=true configuration in all files you want to hide
Still looking for a way to hide "Files" (gnome nautilus) from the menu though :(
