Works great, except for when you want to stop. The stop on win option does nothing, and neither does the stop button.

The other major feature request should probably be an inbuilt rate limit in line with the FAQ. It should bet once a second on low odds, and scale up. It's basically waste resources on both ends if you go faster than the site lets you.
Did you even read the beginners guide? If the stop on next win is ticked and click stop, it will go on betting untill it wins and then stop. If it is not ticked and you click it stop, it eill stop as soon as the current bet is finished.
In the advqnced settings tab, there is a bot speed setting you can use to slow doen the betting, otherwise it bets as fast as the site allows. It wastes almost no resources client side while waiting for the bet to finish, and wastes no resources server side while waiting for it to finish
