- Great extension! absolutely vital for pixel perfect dev :) Would love a feature that remembers the last rules placed, or allowed you to save groups of rulers.

- best so far, somtimes it causes pages to crash so that they must be refreshed and doesn't seem to work in modals. Otherwise very useful.

- Works great. It's fantastic that the rulers stay between page refreshes... so far this is the only ruler I've found that does that seemingly basic function. Just needs some enhancements to make creating rulers easier. Would love to see a mode that automatically highlights elements on the page as the mouse moves over them and creates a ruler for that element when you click. Would also like a mode that allows rulers to snap to text baselines and element bounding boxes. And an option to show guides that extend from the corners of the ruler to the window edges.
