Didn't think much of the interface. It was fairly simple to navigate and had a bunch of features but looked a bit cartoonish and not professional. It was also missing a scheduling system as far as I could see.

I have been developing a highly configurable business management tool that may get commercialised and consequently have had alot to do with user interfaces. This one to me does not cut the mustard, however if it is actively developed it may well start to prove its salt.
