Two things that Bright Eyes can do:

1. Poo on the toilet.
Yes - hooray! He finally did one, out of necessity, in a strange place, but it shows it's possible. Now to bring the skill home...

2. Reach the doorbell.
This sounds trivial, but he has needed to ring the doorbell whenever he enters the front door for years and it has always been a case of me dropping whatever I'm carrying, hoiking him up, pressing said bell and quickly opening the door and plonking him down so he can hear it ring. But NOW... he can reach it himself. Sooo much easier!
