Why is it that so many installed programs that do not show up in the Menu ?
I am using Ubuntu_Mate 24.04.
I try to use Synaptic Package Manager,but many programs are not listed.
When that occurs I have do a search for how to start the program.
I am willing to add programs to the Menu manually.
Use a menu editing tool for MATE to add the apps to the menu manually. Alacarte is an easy-to-use menu editor for GNOME that can add and edit new entries and menus. It works with the freedesktop.org menu specification and should work with any desktop environment that uses the spec (including MATE maybe). If not, search in the App Center for an alternative menu editing tool for MATE.
