So in addition to the items you mentioned, I would add:
1. Modding support
2. Support to build additional modules/adventures.
Although I think these two are a problem with the collab with WOTC, which I don't think has worked out very well. Larian and WOTC have very different corporate cultures and values and likely WOTC doesn't see the value in using this as a platform to build up interest in D&D by letting people have good mod tools.
