Thread:Extension talk:MobileFrontend/useformat key-value pair

I installed the extension and tried to reach the mobile version by appending &useFormat=mobile to a given URL. Nothing different showed up

Then I tried &useformat=mobile (after having taken a peek at the source code, notice the non-capital "f" there). That worked to the degree that the formatting seemed "mobile-ish", but the Show/Hide Buttons still aren't there for the headings

Can anyone shed light on this?

Best, Sandro
