Do you use a preset viewer?

[Arual]

I am currently using a trial version of Preset Viewer Breeze (by the same ppl who wrote the program Preset Viewer v.2.1. Breeze was written so that it can work on Mac, V2.1 couldn't run well on a mac so the guy essentially rewrote the program so that it works on both platforms and changed a few things as well).

Anyhow, I have just a day left on my trial version. Im trying to decide if I want to purchase it or not. I do love that I can easily see styles, shapes, brushes which will help me in organizing them into catergories, but Im not sure what else it would really help me with.

Do you use a viewer, if so, which one and was it worth the purchase?
