Renters and rig owners on scrypt rentals can now see the hash graph live during the rental, as it would be seen from the pool.
Sha-256 and others algos are coming in the next days, as well as viewing the graphs in your rental history.
New stuff is coming in, there is unfortunately some backend work required that has not an immediate visible effect
Also, we do read feedback, our roadmap is more than 100 lines of suggestions "Support provided" limited to some given times only, cancelling a rental, the API, ... Stuff is coming!
I bet clients will ask me why they are getting less than what they pay for...
