Just explored this programm, and messed around with it.
It is simply amazing, the most advanced component out there so far.
It is hard to believe that this system was put together by two person.
The quality of the Javascript, PHP, design, software design, graphics, and even the documentation is like that of a highly-tuned.
I have to agree wiht so many other here: easy to install, excelent documentation, flexible. Simply said, a great program.
I really mean PROGRAM, because it is not a script anymore
