Warpcast should implement $cashtags and improve on the limitations of Twitter. 

Namely: 
1. Allow way more characters 
2. Allow special characters 

This is a little detail that I think expands what’s possible with tokens and leans into what we are already seeing with tickers.

I'd be careful with special characters, that can easily f* up the layout.

But one of the most important changes to me, would be "in-line" answers.

I'm not sure why there pop ups a new window. Being able to reply within the same window is one of the few advantages of Twitter right now.
