  • (2020-02-12) Ryan Leach: Found it impossible to use, Could not see a menu, could not see a hover, instructions in extension description incredibly unclear on how to use. Screenshots look amazing, but unfortunately I was not able to invoke any actions into displaying.

  • (2019-05-08) Adam Sturge: Was looking for exactly this when working on a website. Since Inspector sometimes changes the size of the CSS then it can be helpful to use this. Keep up the great work guys! 10/10 must download
