Not sure how often everyone else experiences this but on occasion I will click the wrong link and have to go back through the fight list looking for the guy I was currently working on. This becomes a little tricky when they are all variations of the same name + number.
I'm suggesting, similar to the way clan members or fight limited opponents are highlighted, adding some sort of orange/yellow tint to the last opponent you battled would make it easier finding the correct bot again.
