    This 'Digital Ruler' looks promising, but still needs work. The 'Area box' is too far away; it should appear next to the drawing tool as you draw. Also, as a web developer, I just need height and width (X and Y aren't useful). Please add the ability to remove the gridlines. Last, but not least, the best rulers allow you to use the arrow keys to move your drawn box around. My favorite ruler of all time was 'Page Ruler Redux', before Chrome removed it.

    I LOVE that the cursor's colour auto-adjusts to contrast against its immediate background, making it visible at all times! Very simple to use - gives height/width (if you don't understand the X and Y stuff) - and easy to switch on and off. I just went through a slough of different pixel measuring extensions (too many, most of them awful) - and THIS ONE WORKS. Knocked one star short of five, because there is a typo: 'Width' is written as 'Wight' by mistake. But I'm keeping this one!
