We've not updated our farcaster frames base functionality for a long time so there is a lot we'd like to do. 
Over 60% of our users have come through referrals which are handled through our web app. We'd love to make this work in farcaster frames since it's an inherently social activity and is a perfect use case for frames. It also drives a lot of transactions on polygon.
Succesful referrals also get users bonuses in our seasonal referrals so it would make sense to also develop a frame where users could see and share their seasonal rewards via a frame. 
Beyond those new features we'd of course also love to just improve our existing frame to make it more performant and easier to use.
