A quick aside for those who may not be familiar with PhotoBars...
PhotoBars is among several tools in the Extensis PhotoTools product.
If you're familiar with (say) Microsoft Word or Excel where you create custom toolbars and assign buttons to them, PhotoBars provides equivalent functionality, though not implemented quite the same way.
Just imagine only having to click a button (with a unique, easy to recognize icon) to invoke Unsharp Mask or Add a "Hide All" layer mask, etc. If it drives you nuts to hunt through Photoshop menus all the time, PhotoBars is a very attractive alternative.

Daryl:
Your ongoing support of PhotoBars over the years is greatly appreciated by many, yours truly included.
It probably says on your website, but for the benefit of folks who aren't familiar with your handiwork, what's the minimum version of Photo Tools one needs to apply the PhotoBars CS upgrade.
Thanks again for all your hard work. KEEP IT UP!
