So, from the Corona Image Editor when I click save all it would be nice to have a click and hold option to 'Save some...' From there a dialogue appears, I can uncheck the passes I dont want to be saved out and then CIE does my bidding.
There are plenty of times that I want to be able to play with multiple light passes in CIE, but in the end I don't really want or need to save them for use in PS. I end up saving them out just because it is quicker and easier than saving out 10 passes manually just so I can skip 4 or 5 I don't need.
