I agree with the premise, but I think that I actually want something closer to the opposite. >95% of the things I look up are dead ends. Because these externalized cognitive spaces have weight and complexity, I often want to just wipe them out completely and start over. I've turned my Safari "remove history items" preference to a short interval, specifically to minimize the cognitive overload that URL completion will have. (I was disappointed to learn that Firefox removed the history expiry setting entirely. All of the forum questions asking for it are met with answers like "We use an efficient database now, so you don't need to set an expiration time!" Cool, but the implementation architecture had nothing to do with why that was a useful feature.) I also use private browsing a lot. Need to check a quick fact on Wikipedia, that isn't directly related to my main work? Private browsing window. Some people are obsessive about keeping their Git history clean. I'm obsessive about keeping my browser history clean. In a sense, my browser history is the workspace imagined here, only with a less efficient UI. Instead of a separate concept of "private browsing", though, I would love it if I could option-click a close button (on a window or tab) and have it erase all history/cookies that were generated by it. That would make history curation much easier.
