==Renaming==
Rumors say it was suggested in Beta that the pencil icon - universal in mobile apps for “can be renamed” - be placed at the end of the team names.

==Short Emoticon==
Unlike the forums, you cannot copy & paste or use a keyboard, so the character length of the emoticon counts against your total. :grin: counts as six characters while :elementholy: counts as 13 characters.
This works better with short emoticons or long but descriptive emoticons.
