This is subjective, I realise, but can anyone point me to the best on-screen ruler? And it can't be browser biased.
I have looked at loads and tried a couple - one was fabulous for 7 days then wanted $30 to let me keep using it, and the latest one is really good, but only comes in pixels - no option to change the scale to cms (although working on three different screen sizes, that might not be such a bad thing).
Any pointers would be most appreciated.
