When a device is selected that has a larger width than the browser viewport it happens that the device selection and/or the rotation button are outside the viewport. This requires you to scroll horizontally in order to change them, which results in bad UX. It would be better if those two options always stayed visible. Or, if that's not possible for some reason, they should at least be placed next to each other. Sebastian
Thanks for filing! I agree the layout gets a bit strange with viewport larger than the browser window at the moment. Hopefully we'll soon have "fit" mode to help here (bug 1213951), but we should still try to do better in 1:1 pixel case as well. I don't think it blocks enabling for now.
