Hi MEB -
Thanks for the reply, but I'm still having a little trouble with this:
1. When I enter the Export persona and select the Slice I want to export, I change the Export Options at the top from 'JPEG' to 'PNG' to preserve transparency. However, the file being exported remains a JPEG. Am I doing something wrong or could this be a bug?
2. Similarly, I think a 'Trim' option would be useful anyway so that I could take away transparent areas and then enlarge the output to a specific size (say, 800px wide). Having a slice do this automatically means the final PNG file is an unknown pixel size. Is there anywhere to make feature requests for future updates?
