this is an amazingly useful tool. if you like making windows user jealous, i suggest installing it. amazingly, i much prefer this tool to the similar xScope for design reasons alone.

The best of the on-screen rulers...no competition. Two new features, scaling and user-defined color of the floating ruler, are wonderful additions. Works great! Highly recommended
