Well can this one support multiple players and more than one person useing it at the same time? The first fullscreen options window is the one that has my praise >>
I haven't taken a look at the triggers yet, but it just looks like another version of the Full Screen Skill System (that's where Thunder_eye's link leads) and the Full Screen Inventory System. These aren't that hard to make once you download any one of these and export the imported stuff. No offense, but it's nothing to special. Now a model pack with all the models and stuff, that would be something usefull.
Anyway, I won't go as far to say it's a rip-off of any of the others, but isn't very original.
