Sorry for the ress, but I solve this in Persona with HTML and CSS, just declarating the Sidebar widget-area in categories.tpl and CSS to fix the categories width.
I'm newbie with front-end, but this "fix" is functional atm.
Yeah, we will add an option like Only display to Admin for global mods as well. https://github.com/NodeBB/NodeBB/issues/4344

add option to display navigation items to global mods
@baris well finally managed to get it working, I was missing to accept merging the branch when doing the pull.... but that was not enough as now it was showing me a problem with the widget essentials... so I checkout the commit for "up widget essentials" and that fixed it for me!!
Thank you for your time @baris
