The tool works great, but I'm a little concerned by the new update - why does it need permissions for browser history?
Works great, both on my Chromebook and Windows 10 laptop. Eye for detail.
This is a great extension. I find this extremely useful. If i could make a suggestion.... allow another unit for pitch gauge. (think roofing)
very simple and easy to use.
Simple and easy to use. Love the new UI!
Does not work on images or jpg's
Really useful and straightforward. I wish you could choose where the 0 degree bearing starts and choose CW, CCW, but other than that its perfect.
trying to move the protractor on my chrome book makes the protractor jump and get stuck at the top on the screen. if fixed i will rate higher.
Простое, функциональное.
it is a good extension and if the pointers stop moving just double click them
