(2017-11-30) Adrian MacLeod: New update is perfect! Works exactly the way I'd want. Loving the toggle feature.
(2017-09-05) Mikhail: I honest can't give it a higher rating until I see an on or off option. On the rare chance that it does work, the outline vanishes in like 1s.
(2017-06-28) nerdoubt: I still don't know this will help me because it only shows the outline, width/height for like 2s.
(2017-06-27) Du Jing: Not work, when open a new pate, just flash 1 second and disappaer
(2017-06-26) Di Wen: Uh oh, it has an invisible `div` inserted into the page, which hides the sidebar buttons I've spent an hour to figure it out.
(2017-06-26) Chi Wai Yip: it would be nice to have on/off feature
