I've noticed that the full-page width sidebar tabs I'm using on a test website's homepage (URL = http://www.wolfmaisontest.com) break apart when viewed on mobile devices (or on a desktop browser stretched to a very narrow width).
I suppose this is inevitable due to the limited width of mobile screens!
But, as you can see, they break apart into separate tabs in a rather ugly and non-readable way. Clicking on the separate tabs opens them without scrolling the page to the tab content's beginning. Worse, a nested multi-column layout within a sidebar tab does not wrap the text within! (see the "Services" tab...)
What would be GREAT is if there were some way to edit the theme such that a set of sidebar tabs are CONVERTED to Toggles (with one visible) when viewed on a mobile device (or narrow desktop browser). That might keep the tabs connected and open them for a viewer more smoothly....
That's probably pretty complicated code, though!...?
