What's the difference between the App Store and Paddle versions?

I’m selling FoldingText both from the Mac App Store and from a Paddle powered license screen that shows in the FoldingText trial download. Generally the two versions are the same, but there are a few differences to be aware of:

  1. The Mac App Store version is Sandboxed, the Paddle version is not.

  2. The Mac App Store version (should) support iCloud, the Paddle version will not… only apps sold through Mac App Store can support iCloud.
