It doesn’t do anything by default, you have to go to settings > zen mods > click the settings icon next to the mod name.

If you set the options and nothing happened then I’m not sure, it worked for me instantly when toggling stuff off.

I’ve started using more Zen Mods recently too, the most important one I would say is Zen Context Menu - which lets you de-clutter the options when you right click anything. There are way too many options being shown when you right clicked the sidebar, but it’s a lot nicer to use now.

this is actually a plot point in the graphic novel Eight Billion Genies, where people would make a wish by reading a really long contract for hours that covers all the possibilities and caveats. You’d enjoy it, OP.

that assumes you know exactly what you want though, which I think most people wouldn’t at the time of making the wish
