The output leaves something to be desired: only 1375x918.

I imagine it could be a popular tool to generate custom desktop/device backgrounds, but the low resolution combined with incorrect aspect ratio (not 16:9, 16:10, or even 4:3) makes it unappealing for that use.

Hi itafroma,

If you go fullscreen (there's an icon for it right under New), you can export a background that's exactly the right size for your browser.

Right now the output is exactly the same size as the input, but it's a good idea to let people download cropped or scaled versions.

Ah, yeah, I just figured that out after trying to piece together why it was such a weird dimension. Standard sizes would definitely be helpful, especially since doesn't seem to take into account retina/HiDPI displays. MacBook Pro set to "Best for retina" produces a 1440x900 image.

Hmm... What browser are you using? I'm on a Retina Macbook, and just successfully saved a Retina-quality image using Chrome.
