Hi,

Here's one I use a lot. It's a Cooler Ruler. Brings up a nice ruler (adjustable) wherever you are on your Computer (always on top.) Lots of nice options available right on the ruler (pixels-inches-etc.)(Even a calculator Open more than one ruler at a time and simply drag them around to the positions you want (vertical-horizontal.) I keep it in my Launch, cause I measure a lot.
Oh yeah, it's Free. http://www.fabsoft.com/pages/Downloa...ads.htm#Cooler Ruler

Enjoy,
