One of the missing features for nvim-gtk vs gvim is the ability to use the right-click context menu (vim calls it the "PopUp" menu, but it is unrelated to the nvim-gtk Popup for completion). I know that the mouse is anathema to many vim users, but I find it useful to put some commands in the context menu that are useful, but used to rarely to commit to memory.
