Lol i was looking the name of the lib i used in one project and it's yours github.com/zachdaniel/t...

Btw i was reading about Surface and if i understand correctly is a compiler on top of liveview. Looks cool but i think something like tails is more close to the metal and easy to port. I'm still debating myself

ok so in the case of an if else would you normally create both cases? e.g.

Typically yeah, but you could also add a tuple on the right hand side `{“class”, {condition, else: “fallback”}}`?
