I need something like a task list that i can easily add and delete. Something really simple similar to that in MS Outlook tasks but I want it to be available on the desktop. I want it to be transparent until I press an F key which toggles it on so that i can read the tasks and delete the ones i've done and add any. They would be simple one line tasks like "download patch for litestep" or something.

Any themes or modules already available with this kind of thing??
