Maybe it's just me, and granted, it's not a big deal, but the spot where the unspent AAs are listed isn't big enough to show how many unspent AAs you have if you have over 99. Just noticed this when all my trees got reset and it told me I had 20 unspent AAs. I had a few more than that (180).
Not really a big deal but may be something to fiddle with when bored.
