Used menulibre to delete a couple of menu entries, mostly because I saw the greyed out reference in panel prefs command section. What it did was delete almost every other menu entry except for the one I selected, and the few it left got moved to a new "other" catagory it created. So what's left is this "other" catagory and the accessories catagory which contains nothing but the 2 launchers I had selected to delete from it. Dev is unresponsive on github, and there are similar issues from 2 year ago. Massively inconvient as there seems to be no way to restore the menu other reinstall. I think this package should be removed from the repo and the reference in panel prefs removed as well.
