Browser bookmarks don't work well for me. I find hundreds of great pages that I want to visit again later, so as I bookmark them, my bookmark list expands out of control. I've tried organizing them, but that takes a lot of work and the categories I choose get outdated within weeks. Eventually I get frustrated and just start a new bookmarks list. I've repeated this cycle ten times or so.

Here is an idea that might solve this problem. I'd like a search box that finds terms among the pages I've bookmarked. I don't mean it should search the bookmark titles (I think some browsers already do that), I mean it should search the text of the bookmarked pages. This could be enhanced by a long-lived cache and spider. There might also be some way to automatically organize the bookmarks using common keywords.

I wonder if a search engine could even take this to the next level. If the search engine has my bookmarks, the engine can use the bookmarks as advice for the ranking algorithm. That way, when I type "python", all of the highest-ranking results will refer to the programming language, not the snake.

This idea came up because I'm trying to find an interesting project that tries to combine the advantages of a command-line interface and a GUI. As you select nouns and verbs, it narrows the field of possibilities until you've constructed a complete command, then the command executes. It was built with Qt and had a series of columns. I saw it on the web once but I just can't seem to find it now.
