Got it. I’ve not activated it YET, though…
Widget Control settings are not in the wp widget page (I’d be very curious if you could elaborate on that :) ). For people having more widgets than pages, that’s fine, however…
…as I see no more support for url and wildcards
…when having to deal with way more pages than widgets, on a page, with a large amount of children pages, you get infinite clicking mileage to setup each and every children page manually

…meaning upon activation of the plugin, I’d have to visit each of my 130 pages settings :/ (tell me if I missed something)

I propose a solution here (widget control on categories is ok as it adds extra control I guess ^^)

It’s not perfect as one would still have to navigate in all parent pages for setup (if I’m not mistaken)
My (temporary) conclusion is that a widget controller had better be in the wp widget page settings to remain 1 click away from configuration (or not?)
