0 for 2 thus far in miniFTOPS. As far as my complaints are, they are really simple things. Implement a slower blind structure. Output hand histories in a text based format. These things would improve them greatly, and would be absurdly simple to implement. Like, I could do it in 1 day with acess to their code and a 4-pack of monster simple. There is absolutely no reason for them to be stubborn about those 2 issues.
I have other issues with them as well, but those are personal preferences. I'd prefer a better slider, and prefer that Realtime HUD worked with them, and prefer a 3 button interface that's moved to the bottom right rather than bottom center, but those are things that would not stop me from playing there, and things that certainly can't be changed overnight. But my complaints stem from things that can be, and should be.
