The other day, I discovered that in Firefox you can hit ctrl+shift+M and a dropdown appears at the top of the browser window, where you can choose popular cell/tablet models and see how well your site works at those sizes.
I building a site for a friend in Wix Editor - (I know you can view the site in a generic phone sized window) but for checking out how the site works in landscape/portrait tablet sized windows is a tremendous help.
Any chance this can be implemented in Opera please.
