Basically, the title. We could use a battle log chatbox to see what happened in the previous rounds. Sometimes, I alt tab and I'm not sure what happened to my attack, or want to see what pokemon I just killed because I was mindlessly grinding.

 

A battle log is just useful overall. You already print the messages to the screen, so printing them to a log shouldn't be hard.

 

Also, as a side note: When you run for a pokemon, it says "You have run away from X" and it should be "ran".

this is also very helpful when you loose count of how many turns weather/screens have been up or other multi turn attacks.

Up for visibility, this is important, especially for competitive play

oh yea, also would be useful for showing screen shots of battle bugs.
