I admit, I was putting off setting up my Metropol. >_>; I had only 3 categories (big tabs), but I wanted to use all the ones that were included (6) otherwise, it would annoy me. Unfortunately, I couldn't think of anything after the 3 categories, those were the most important to me...
I, also, didn't want to set it up yet for a few reasons:
#1) I ordered more paper from KiddyQualia and wanted to use it for the sub-sections in the big tabs (I think I just confused myself Lol)
#2) I couldn't figure out how to do my dividers. I didn't want to leave them plain :(
