GloboNote is a useful application that allows you to add notes right on your desktop, like the Windows 7 Sticky Notes but with more customizable options.
Notes are shown with a border and a title bar. Also they can be rolled up automatically, showing only their title right on the top of the desktop. These and other parameters can be adjusted from the preferences window. For example, the size of the notes when they are rolled up can be made even smaller. You can change their font and size, add a transparency effect, change their colors, and more. The advantage is that each note can be configured independently from the others. Besides, you can create groups to order your notes.
Other important thing to bring the attention to is that you can use the notes as reminders. With this feature you can schedule reminders, playback sound of different formats whenever an event is activated, configure snooze timeout, and create repeating events.
Among other options you can export the text to clipboard or .txt file, insert images, and attach files to the notes.
With this program you can add more functionality to your notes and have your desktop more organized.
