Bring back tablet and browser editors

Bring back the tablet and browser views for the app editor. The mobile phone editor view is too narrow.

Not all apps are intended for phone use. I embed apps to a website. Editing wide apps in the phone-size editor is painful. I need more horizontal space to place elements side by side. I don't think my use case is unusual. I'm sure there are others who need a more spacious editor.

According to Openasapp support, the tablet and browser views are from "an old version and no longer available". The buttons can still be seen in documentation screenshots and the frame elements are still in the page HTML but hidden. Bring them back, please.
