Well I'm new here, so this might be a dumb idea, but here goes nothin':
I thought it was kinda annoying when you have loads of eggs and want to incubate them all, so you don't have to wait for them to be ready when you want to hatch them. But then you have to sit there and incubate all of them one at a time and blah de blah blah...
soooooo...I thought of the "Incubate All" button for the hatchery :) Or there could be check boxes next to all the eggs and you could go through and check off th ones you wanna incubate and when you are done, you hit a button that says, "Incubate selected eggs" or whatever XD
Just an idea ;o
