What do you do if you want to paste something from an application that does not support the clipboard?
Middle-button paste to lyx, C-x, paste text as paragraph. It is a bit more complicated, but IMHO lyx does not have to provide a menu item just for this very special case (and special application).
If you are going to rename that you should use "plain text" instead of "text", since that is the term we use elsewhere if we mean
Yes. That would be better, and making UI clearer is my first priority.
You should IMHO try to figure out why these menu items have been implemented before removing them. We should not remove these features. The code is needed anyway, so they don't cost anything, and there is a sensible use case,
Again, we should not cluster the menu just because the feature is there. Bo
