I like to do multiple version of a photo, but I often keep the more normal shot applied. If I want to share one of these versions I have to go through the process of:
1. Opening the photo
2. entering edit mode
3. applying the version
4. share it
5. switch back to my preferred library version
A suggestion I have is that for photos with named versions add some sort of expander feature that can be opened and collapsed. Think like the expander arrow on folders. It would allow easy access to those versions, while allowing you to also maintain a clean looking library. It would also provide a visual reminder that you have saved versions of a photo.
