Columns for NIP-51 lists and relay based columns would be very powerful indeed.
I mentioned to will about #4 in the past and he said he felt it should function like that too. So, maybe we'll get that soon.
1. All the things nostr:nprofile1qy88wumn8ghj7mn0wvhxcmmv9uq37amnwvaz7tmwdaehgu3dwfjkccte9ejx2un9ddex7umn9ekk2tcqyqlhwrt96wnkf2w9edgr4cfruchvwkv26q6asdhz4qg08pm6w3djg3c8m4j mentioned.
2. Relay based feed columns.
3. Kind 30000 list based feed columns, AND the ability to create such lists from within the client. Preferably with support for private lists. I like to have a list of folks I know are local to me, but I also don't want that information to be publicly available.
4. Support for multiple hashtags in a single feed column.
I am sure I can think of more as I play with #NoteDeck a bit longer.

I have really been enjoying popping over to jumble.social and viewing my WoT relay's feed. I have found new folks worth following that way. And now with Algo relays... It would be really nice to have.
