What was crappy?
Performance?
Number of users?
Crashes?
Interface?
Slow, unresponsive, interface was sub-par to say the least, no crashes my side, and I suspect very low numbers of users also helped the negative experience (though I have no actual numbers, just speculating) ... trading graphics very sucky.
All in all, I didnt mind the interface, it's not priority, like our own QT... but the experience was slow and buggy
