This suggestion is minor and I'm not even sure if XF would be able to do this. When you uninstall an add-on from the control panel, it does just that. Good. But you also have to delete those files from your server. Sometimes, to make sure I delete all of the directories from the add-on without...
I just installed it now and it seems to work fine.
Yeah I did that, only to discover it didn't add any features that 2.2 doesn't already have and the features it added just made the user interface more likely to confuse many members.
But all of this is missing the point that a a tiny bit of information added to the description and a couple of screenshots would have given me all the information up front to tell me that I didn't want or need this addon. What's so hard about that? And it's not like @Xon is a novice in this regard. He does include information in his other addons.
