Dave introduced me to the list builder, I think its great. Although I hope that it won't turn out to be too specific and less flexible when it finishes.
An example of the direction that maybe a problem is. I wan't my check box on the right side. I think this can't be done on the adp/template of the list. I haven't use the paginator of the list builder, but it would be nice if. The future direction is that the paginator is not too coupled with the list builder. Its also a bit hard to customize your template, you need to use noparse, or some other trick. Read the list-procs.tcl code. Its not something a designer level developer may always have.
All in all, I think the list builder is helpful to me. Just giving some feedback on it and hopefully it will get better.
