I love this app, but...

still there are a lot of crashes (I am using it with ipad2, which complete crashes everytime use this app, so you have to reboot ipad). The UI is great and you can do a lot intuitively. If they fix the crashes and add some useful graphical filters like line drawing or a comic filter, this could be one of my favourite photo apps.
