I understand that there are a few issues but its easy to fix them, without having prior experience on app development..
Ease of use
Hell yeah!! Its so simple even my little sister can use the app. I really cant say more about this!
And yes their support rocks. I send them mail via "contact us" which is on their website and they answered really fast, which helped me alot
There is currently a poor documention, helping you only about the basic stuff, but its enough for a start. I hope they improve this.
