Jim Mckay has SSBookmarks - a class for getting SSBs. I was able to use it to get SSBs working in the app I’m using.
One Caveat - it does not work when running the app in the Xojo IDE. The preference folder that uses is different from the one a built app uses.
I needed this because saved files in my app often include links to audio or video files that have to be loaded along with the rest of the saved data; and for opening items in a Recent Items menu.
