When the Interesting/Ignored tags feature was first added, the preference to hide questions was in the sidebar.
I liked this, since most of the time I don't mind the questions just being greyed out.. but there are times I want them hidden. Having it enabled all the time seems quite.. destructive (from my view as a user - obviously it doesn't actually delete anything)
Current I have to go into my profile, into my settings, click the option and navigate back to the page and reload, just to toggle this..
Seems quite a lot of clicks, especially given that the questions are hidden using Javascript (if I'm not mistaken)..
