A place for tasks that aren't urgent. They stay out of your Now list until you need them.
Tip: to reorder folders, drag a chip sideways (on touch: hold it, then slide).
Every device that should show the same board uses the same code. Treat it like a password: anyone with the URL and the code can see the board.
Normally not needed — changes sync by themselves. Upload = the cloud takes this device's version. Download = this device takes the cloud's version.
Import adds anything that isn't already on your board — it never deletes.
