DNoter
DNoter essentially lets you do the exact same thing,
except instead of sticking the paper note on the monitor, you place
the note wherever you want on the screen. I know that sounds cool,
but what if I told you that you can set the transparency of the
note so you can see items in the background? Even cooler! Another
nice feature of this application is that it will save the location
and contents of your notes so that if you close and re-open DNoter,
your notes will be in the same spot. DNoter also includes a couple
other features like the ability to hide/unhide a note and to
lock/unlock the note's location.
