The export image sequence option is great - and exporting the sequence as a ZIP file is a good idea as it makes the file managment nice and tidy.
It would be useful though, to be able to just export a single image as a jpeg or png. This would come in really handy when creating backgrounds and guides in Autodesk Sketchbook. Being able easily to move grids, guidelines, background images and other elements back and forth between Flipaclip and Sketchbook (or any other drawing app) - whilst keeping the exact size and positioning of all graphic elements fixed - would be a real improvement.
It is, of course, possible to do this now, but it's a bit long winded. The ability to export a single frame and have it appear immediately in my image gallery would be great.
