Write Post It notes on your desktop that will stay always visible, with StickyPad
StickyPad is a convenient Windows freeware that lets you place sticky notes on your desktop. I have tried many sticky notes tools, and this belongs to the best.
You can type notes to yourself, set meeting and appointment reminders, keep track of a to-do list, and anything else you would do with paper notes. Your notes can be printed, pasted into other applications, or emailed to coworkers.
You can make notes translucent and have them float above your other windows, so you can see both your note and what you are working on. When you log off, StickyPad remembers all of your notes, and when you log back on, your notes are still there.
Other features: shortcut keys, so you can write sticky notes from any Windows application without using the mouse; help system in case you get lost; shadows; additional access to 4 frequently used windows programs or documents with shortcut keys or icons at the StickyPad menu.
Notes created with StickyPad will not disappear, if you use a program like Wallmaster to hide desktop icons.
