+1, yes please. Must have. I'm sure you'll put it in soon, and thank you in advance for that, but for now, I'm going to sound a bit shirty, for which I apologise, also in advance!... But, think of it like this - who are 'you' to tell 'us' what aspect ratio we need our images at???!
Looking awesome though - you're true trailblazers!!
oh, and PS. I was looking forward to giving the beta a good look tonight, whilst editing some stuff, but am now going to have to go back to Pixelmator because I need to do a load of cropping and, guess what?... the size I need to crop to isn't on the list!
