It's very cool. I played around with it last night. Some issues I noticed last night:

1. Still pretty slow making payments.
2. Frequently payments would time out (but still go through).
3. I paid from WoS to this wallet, but when I would try to pay back out to WoS, it couldn't often find a route. It could not consistently find a route for payments over 2k sats.

I am sure these things will improve with time.
