Any advice on good starting points if I want to make my own mini app here? Where do I start?

What do you want it to do? The official docs are pretty good. Will share a few demo repos below too.

added support for the new sdk actions (swapToken, sendToken, viewToken) to my mini app starter project just in time for builders day.

if you're planning to hack on a mini app, this starter is the fastest way build and deploy. 

you can also just play with the mini app to see how those new actions work and look like in warpcast and other clients.
