I just checked it out, not sure how it's any better than DBT's? Seems fairly generic and even the OLD likes system by Abe was more robust. Not trying to be a jerk, I just don't see how it's "superb" at all. =)
The only thing I do like is the location of the button, but as DBT has text in their's and you can make whatever buttons you'd like.. it makes sense where it is. Maybe I'm missing something though and you can shed some light on it?
