Have current clan rankings shown on each clan page. It would save the need to ctrl+F a clan's name on the clan list to find its ranking.
Expert mode, where all confirmations (eg. cancelling buffs, accepting/kicking bots) are removed. Could also include removing the 'changes saved' box whenever you change something. I don't know much effort this would require, but it would be nice to have on certain bots.
A message in red at the bottom of the last fight telling you a buff has been used up, similar to when your gear breaks. I usually notice when a buff starts flashing, but if the fights are long I sometimes forget by the time 10 fights have passed and don't notice when it disappears altogether.
There was one other thing but I've forgotten what it was :p
