lxqt menu customization
From thelinuxwiki
create a <file>.desktop in ~/.local/share/applications/
example .desktop file
[Desktop Entry] Type=Application Name=my example app Comment=hahaha Exec=/usr/bin/myapp Icon=23AC_misc.17.png Categories=Application;
the Icon exists in a subdirectory of ~/.local/share/icons/
i am not sure how the Categories work, this shortcut shows up under "Other"
