ITSD Organizer, also known as
Is There Something to Do? strikes the right balance between sticky notes, personal organizer, and reminder programs. ITSD has plenty of keyboard shortcuts to aid navigation, but unlike so many other apps in this category, it includes an expanding monthly calendar view. For example, if you enlarge the program screen size, more monthly calendars open up along the right pane. You can also choose to turn the calendar off. All of ITSD's features are within reach of your mouse using the toolbar or view panes or with a keyboard shortcut, making the program both fast and easy to quickly add a note before you forget your thought. Each note includes a notes section for further annotation.

Above is its Tree view, where the user can define categories and subcategories as nested folders. The program provides an option to open and hide the program to the system tray using the Scroll Lock key. Even better, you can not only customize a few of its hotkeys, e.g., for adding a note, but ITSD includes a neat "Quick Notes" feature with a hotkey activation that you choose. Just select any text from any program, hit F11, and ITSD copies the text to the notes section of a new note.

That's keen design borne of consideration of what makes a good notes application.
