If a group of Ages are tied together (like Eder Gira and Eder Kemo, or Kadish Tolesa and the Kadish Gallery), then installing one should (offer the option to?) install the whole group automatically.
Likewise, I'd like to be able to create "dummy" Ages that don't actually install Ages, but only contain dependencies, so that I can create a one-click install-me package for "all the Ages I think are really well-done" or "all the Ages that are part of the XYZ storyline". Or, for that matter, "all the Ages in the repository".
I would also recommend that the dummy packages have a separate section: OfflineKI, Extras, Packages, Ages.
Edit: It has been explained to me that grouped Ages are generally installed as a single package. I would still like dummy packages, though, as a form of tagging.
