Edit: Remove Background doesn't allow to save with transparency
In the Edit module, there is an option to remove the background. This appears to only enable replacing the background rather than allowing a transparent background to be saved. When downloading, it's already a PNG instead of a JPG, so it seem that the intent was to enable a cutout function.
For this to be really useful to Express, we need to be able to send over a subject with a transparent background. Otherwise the feature is pretty much useless.
Please enable downloading of a PNG with the background removed.
