Has there been any demand for a community based campaign designer for the app? FFG could also introduce a hub to download optional community campaigns.

Other than that...

1. Would like campaigns that used more than one expansion (Hoth + Bespin etc).

2. The way the upgrades works is a bit linear. I would life it to just use the standard end mission upgrades, tell you the points, and then you decide for yourself. XP cards especially are too linear.

3. Longer campaigns of 8-10 missions and get the app to reintroduce occasional forced missions.

There's hope for a campaign designer ... though I suspect more likely a non-app design.

FFG released one [physical campaign editor] for descent 2nd edition, though they haven't updated that terribly much.

Getting Disney/LFL approval for an official IA campaign editor might be something impossible or too much for FFG to bother.
