Recently I added one that just cats a file called today.txt.
It was meant as a quick and dirty "NO, REALLY, YOU NEED TO DO THIS TODAY" todo list. It's always there, always visible (I don't put windows on that monitor), and was meant for quick notes of things I need to make sure I take care of today.
I've got items listed every day thru friday, and the "ASAP" section is so far down the page that it doesn't even show up on the screen.
Mind you, there are several items under Tuesday, and thursday and friday just say "JOB", but still. I've clearly gone well beyond the intended purpose of this thing. I think I need to start doing some of the things on the list for today, before it gets completely out of hand.
