Adobe Plugins pages

If you're in the mood to explore filters and such, you can either go to Filters>Browse Filters Online, or just go to the Adobe plugin listing here.

This gives you a pretty complete list of plugins and some brief descriptions of what they do, as well as links to the sources.

And by the way... Nik plugins ALL support Smart Objects! They act just like a Smart Filter, and let you go in and re-edit and everything. How cool is that?
