I think WalletConnect support for more chains, especially THORChain, would be popular with our users. Trust wallet is the second most popular mobile wallet in the industry, and was one of the first to support RUNE, so a lot of people have RUNE on there and use WalletConnect + Thorswap for LPing and cross-chain swapping. It's generally a good UX but unfortunately Thorswap adds their own fees on top of the protocol fees!
