I think moving feeds will be a common new user need because of this behavior:
* Add feeds to just the Home channel by default (for ease/convenience of reading all in one place)
* Home channel gets too busy
* Create a second topic or group-specific channel to partition off some of the feeds which may only be related to a specific community, organization, company etc.
* Try to move those feeds from the default Home channel, and realize you have to remove and re-add them one at a time, which feels bit tedious
