editing applications menu?

[Ulli Horlacher]

I want to modify the application menu (Xfce 4.12).
When I call Setting->"Menu Editor" the program menulibre is started.
I can only modify or add new items, but I cannot remove items.

For example, how can I delete the second item "Mail Reader" in the main list?

And I still have the problem: when I change ANYTHING with menulibre the
application menu is gone. Neither right-click on desktop background nor
"xfdesktop --menu" work any more.
I have to logout/login to have it back.
