I am one of those people who feel there's a certain amount of meaningful and useful context embodied in the last position of things... the files on the Desktop, the junk on the table, the books out of the book shelf, the tabs in the browser.
As a consequence, I can shift context easily because all I have to do is scroll back to my prior workspace (physically or digitally). However, to remain effective, such a strategy requires a strict policy of no interference (nothing irritates me more than people reorganizing my stuff - which is why I insist on doing my own cleaning).
Sometimes it gets out of hand. This week I closed all my browser tabs and realised the left-most of them had been open for 3+ months. On the other hand, it means using mental powerups like RCS/VCS repositories, todo lists, and project documentation becomes second nature because they are all free stored-context extensions.
It's the mental antithesis of inbox zero - notbox infinite.
