I used to have a nasty habit of opening a text editor during the day and taking random notes during phone calls or as I worked. Several forced restarts (administrative, accidental or hardware related) forced me to start using those sticky-note apps. I've moved to Joplin now (very structured, supports markdown, syncs to dropbox periodically, is multiplatform)

The browser thing resonates though. It's not just which websites are open, but what state they're in (ie: logged in, midway through filling out a long form or survey). In a pinch I'll just 'kill -9 firefox' so after the reboot it automatically restores tabs and windows, but it's still messy. Sites that require authentication will just bounce you to the login page and may not "remember" where you were trying to get to. Maybe we need hibernate for browsers.
