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

Slowly moving Home to an algorithmic feed over the next few weeks. We think this is the best UX for most users, esp. new users. The algo will take into account following, interactions and onchain.

We will also be adding a Following (simple reverse chronological) feed option for those that don't want an algo.

wow, are we finally stepping into this? I thought it won’t come so fast because we cannot even search others casts yet.
