Im actually surprised that the popups and alias editor is still around. Both can be done in the Remotes editor. With my other suggestion to make the Remotes editor Treeview, maybe down the road it would all be in one window and mirc will be intelligent enough to figure out that you're on an alias, remote, popup, etc. I'm not saying the above SHOULD be done, Im simply saying Im surprised the current method is still around.
Back to the original suggestion, sure, sounds good to me
