nice job so far.
But it would be great when the before/after image size can be adjusted. I believe we don't need more than 1.024px in either dimension.
When a tut is done on a 11.000x3.600px pano the resulting before after PNGs would be ~ 120MB at the moment
With a 40D RAW one PNG still would be at ~12.5MB.
Whoops . This is a very good point, and we're adding it to our "todo" list for future releases. It hasn't made it into our most recent release (coming out in the next couple days), but we're hoping to make this improvement soon.
