Version: (using Devel) Installed from: Compiled sources Currently when you delete entry in kmenueditor it will set it as hidden in your local menu file. It stays like that even if you remove that entry in global menu (for example by removing package that created it). If you reinstall it later it's still hidden so the only way to make it reappear is to create it by yourself (but that will just make you have 2 entries of which one is hidden), edit XML file by hand or remove your local menu file completely. It also affects kmenu when you move entry from one category to another. Option which I'd like to see is GNOME's Alacarte like checkbox instead of that delete button. And possibly delete option for locally created entries.
