Feature I'd like to see added in 2015: Once-per-day faucet bonus of +100-500 satoshi that increases with how much you have wagered since last faucet claim but it always at least 100 satoshi.

Also I tried getting a primedice signature but the max signature length is limited to 140 characters and none of the ones on the thread you linked would fit....
Maybe the limit was recently imposed or lowered?
