Any time a user can manually add something, they must be able to manually delete as well.
A few people have already talked about an issue I have on both iOS devices: duplicate servers; for some reason iOS seems to only add known servers and does not seem to remove them automatically.
All I was looking for was a "Delete this server" under the server info, but instead I had to uninstall the app and reinstall it.
Adding without deleting inevitably leads to cruft.
