We really need a top level filter for figures (V4,Dawn,Genesis,etc) and a split for required software (Poser, Vue, DS, etc). Since there are now products which do not mention this in the description or title in the store the chance of accidental purchases is much higher as before.

Using the filters at very low level as is done now is way to complicated and labor intensitive. Shopping should be fun and not work

My personal preference would to be to have exclusion filters as well so you can filter out the things you are not interested in
