You are devel I presume - I said rubbish & there is no “<div id=“main-outlet”>” ? Inspect html source is all I can do.
Did try my best with the picture, sorry.
Or perhaps even better - ? - make it a part of that main-outlet, place it a the top, above “General | all tags | etc…”
Perhaps… as a dual-choice user option (as with colour), between ‘as-is-now’ & ‘inside that main-outlet element / align that way’. Thanks.
