Few things changed. Uploads from a stream will now use a unique asset tied to the posters profile. So the asset will always be profile.PROFILE_ID.uploads. This includes the folder they're uploaded to. Regular profile streams will show these uploads, but what it means is you could keep stream uploads completely hidden or be a separate gallery if you so choose. Next up is if the upload is a photo, video, or music file it'll bypass upload approval as configured for profile galleries. Files will not ignore approval if enabled. I've also implemented management of the uploads directly from activity edit as shown below.
So this functionality is more or less done for activity. It'll be extended to also work with comments. Then parameters will be added to toggle uploading off and on. You won't have to wait for CB Gallery 2.1.0 for this functionality either. Once implementation is complete and testing is done we'll release a build with the functionality ready to go. I'm expecting to be done early next week with this implementation.
