If anyone wants a sneak-peak at what I'm doing, I've checked into the branches directory. It's not done yet, but it is populating the UI from the DB, and writing back out. I'm working now on switching my manual wiring for QDataWidgetMapper, which should make things much easier. Then I just need to set new hot keys for rotating through the ocular & telescope choices. Then it'll be done.
I think that overall, introducing this will only expand what we can do with Stellarium.
