Larger Export Size

I love this service! Use it all the time. It would be huge if we could export a PNG at a larger size than 96x96. It's not difficult to open up the SVG and re-export, but it's an extra step that would save a lot of time.

Why would I need an icon that large? Right now I'm creating a website that has big headers and an icon for each header. At 96x96, the PNG still has some blur. 256x256 would be a good max size.

Thank you!
