1. make is as easy to 'bookmark' stuff as possible -- with a single hotkey
2. make it as easy to search over bookmarks as possible -- also ideally with a single hotkey or as quick as you could do google search
My way of achieving this is using org-mode files for 'bookmarks' [0] and using emacs/ripgrep to search over it [1]. Additional benefit of org-mode is that it's very easy to add notes, priorities, refile bookmarks, so the most interesting stuff propagates through my notes, and I don't feel bad about missing out on information that I don't have time to process because I can always quickly find it when I need.
