This extension displays the inner width and innner height of the screen
Chrome has recently changed the way width and height of the current screen size is displayed while using the developer tools. I like the new responsive system, but find when I am using it I lose real estate on my screen. This is fine while I'm plugged into an external monitor. It becomes an issue when I'm on my laptop trying to maximize my screen space. This will simply put the pixel width and height for the real estate taken up by the screen into the upper right hand corner. I might create a config file to offer color and placement preferences in the future.
Hope you find this useful.
Fixed issue where fixed headers would hide the extension by raising z-index.
Fixed issue where sites inherited font-size and/or font-family was illegible.
