Ah, such a nice term! "Saving string" is part of my approach to doing any sort of long term project. I'll usually start in "diffuse mode", during which everything that enters my brain gets insta-spooled into good old org-mode --- scripts, links, data, sql, todos, checklists, copious notes, the whole nine yards. Then at some point I copy over actually relevant stuff (which only is obvious post-facto) into a fresh "focus mode" variant and execute based on that.
