Jesse Gilbride (ID: 000000e29c31c98c) Voted 4 ★ - Updated 03/24/2016 Seems to work, but I have 3 issues. (1) I'm not convinced the pixel dimensions are correct for all of the listed devices (eg, "Phone - Galaxy all models" has width ~250px wide, and it should be 720px) and it would be nice if the rendered dimensions were shown somewhere, per each view. (2) The menus in the overlay/modal have a white background and the text of the selectable options is white, making it appear there are no options unless the user does a mouseover on them. (3) I'd like to see the extension working on pages without having to add the domain first. Simply clicking the extension button should do it.
