If you right click on a panel plugin, and accidently select "Remove", the item is deleted. It would be nice if the panel had a configurable option for confirming deletes. Sometimes, it is trivial to recreate an entry, but sometimes, if you have a launcher with a submenu, and you delete everything, it can take a while to put it all back again. Reproducible: Always Steps to Reproduce: 1. 2. 3.
For launchers with a menu there should be a warning (unless the menu is empty). If there isn't that sure is a bug. I thought the current situation was a reasonable compromise between protecting the user and patronising. Personally I find 'Are you really sure?' type dialogs very annoying.
It seems as if I get the confirmation box now when deleting a launcher with a menu. I'm not sure why I didn't get it before. On the other hand, as you said, I do not get the confirmation box when deleting other entries. While I can understand how this would be an annoying behaviour to you, I'm sure that you can understand that some users might find the confirmation helpful. Maybe a panel option for "confirm deletes" would give everyone what they want?
I'm going to resolve this bug as WONTFIX. For 4.2 I don't want to change anything unless it is absolutely necessary and for 4.4 there is a warning dialog in all cases. Thanks for the report.
