I think these are “nice to have” features rather than absolutely essential, but:
For 1. I could deal with just being able to download my list of subscriptions and upload it to another server. That’s the only bit that’s really slow to copy over by hand.
For 2. I think the main thing that really would benefit is the ability to search all active communities on all servers. The way it is now is alright if there are only half a dozen really active instances whose communities I might be interested in, but it doesn’t scale if there are hundreds of servers to check out. Probably the more important of the two IMHO in the long run.
