I don't disagree with you. I committed it, because it is a development
branch and it is easy to change. I find it easier to discuss starting
from an existing implementation ;-)
I agree that having the arrow direction and menu popup in the same
feels a bit wrong, but it does use the menu positioning calculation,
so if we still want that it is more efficient to do the calculation
I think adding the xfce_panel_plugin_register_menu() call is a good
idea, since people tend to forget that.
Maybe we should reopen the bug report and discuss API changes there?
