Hello @Stennie_X,
I gave it a quick try. The mechanism you describe (mute categories and switch to them via a adding a URL parameter works absolutely fine.
I need to use the above process a little bit more, after a first test it feels as it the muted categories are fairly far out of focus. As of now I tend to like the option to “watch” certain categories and filter with state=watched the combination to filter watched or tracked seems not to work, this would be nice.
Regards,
Michael
