This is so simple I can't believe I can't find apps that are good enough for this one!
I want an app that lives in your taskbar and runs all the time (starts at startup, runs all the time unless you exit it) and when you rightclick it you get simple options like "red, blue, black, green". No more colors, only those. It will let you "draw" on your desktop wallpaper, and the scribbles will be autosaved (so if you reboot your computer, the notes will still be there).
I have seen apps like this before, but they have disadvantages...
-The good ones are not freeware.
-They have big chunky toolbars instead of a simple taskbar icon.
-They have too many unnecessary colors. (Who needs to scribble captions and reminders in pink? And what's the difference between scribbling them in dark blue and light blue?)
-The app is like a transparent window, so when you are using it you can not use the desktop icons. The app I want should be "integrated" with the Windows desktop wallpaper, so that you can scribble AND click the icons without having to close the drawing app.
