- For years and years I've searched for a tool that could measure angles. No learning curve here. Accuracy up to 4 decimal digits. Zero-angle (+ x-axis) rotatable to any angle. Click- nudge to get an angle vertex exactly over a point. Zoomable. There are other options and most are adjustable. Beyond imaginable! No improvements left for me except going outside the browsers!

- The tool seems to be very helpful. However, the numbering system on my protractor is counterclockwise and I am unable to rectify the problem [90 is 270 and vice versa]. I've tried uninstalling and reinstalling multiple times and it appears to be the default. Please help!

- Really helpful for me. From my window I can see a church spire on the horizon, about 4 miles away. I took a reading with my compass (297°) then, using the protractor, I centred it on my location in Google Maps and set the line to that reading. Lo and behold the line went very close to a church marked on the map that was actually 4.14 miles away! (The church was St. Jude's in Hampstead, London. Download the protractor and you should be able to work out which street I live in!)

- This extension is great! I would suggest to make "clockwise" rotation AND 0 degree at the North to make measurement of North bearing much easier. Thanks to the option page, I can customize that by my own. But I would suggest to make it a default option to save everybody's time.
