New UX on Warpcast mobile: channel icons

- Channels now have visual icons
- Discover, join and leave channels by tapping the "All" button (you no longer need the NFT to join)
- New Books and LA channel experiments
- Renamed Following to Home and Highlights to Trending

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

Cool stuff 

One thing you may want to consider is how to educate new users on how the channels work

It’s not obvi that you have to post deliberately into a channel vs it being filters on the main feed

Also, nice to see the Follow button on channels 

Do you plan to write those Follows to the protocol? Would be great
