How do you add new application to this "All Applications" menu (and optionally to some of categories) without using GUI "Edit Applications" menu (named "KDE Menu Editor")?
It may sound like a simple task but I've already spent several hours on this with no success.
When you download an app instead of getting it from package manager, you may want to add it to Application Launcher so it will not get lost.
I have myapp.AppImage file, it's working, I've created .desktop file and tried to place it into some system directories (e.g. ~/.local/share/applications/myapp.desktop) or calling xdg-desktop-menu install myfile.desktop but to no avail. New app doesn't appear in All Applications or specified category, it appears only as a search result, when you start typing its name.
Creating new menu items with GUI "KDE Menu Editor" affects "/home/user/.config/menus/applications-kmenuedit.menu" XML file, but this file doesn't look like it should be edited manually.
Can you please try adding custom executable to this menu yourself and see if you will succeed? Am I trying to do something quirky and is wrong about expecting this task to be simple?
My system is Kubuntu 26.04, KDE Plasma 6.6.6.
Yes, I've tried quite a lot of commands and combinations, restarts etc, but seems like problem was in some obscure tag in some obscure XML file which I've never touched before. I've added a comment with solution.
