The following review written by one of the Software Informer contributors applies to version 3.1
Get rid of your physical sticky notes by replacing them with cozy virtual ones. Efficient Sticky Notes Pro helps you to achieve this in an easy way. It allows you to generate virtual notes and reminders and locate them on your desktop as if they were stuck to it.
You can set them to be transparent, so that they do not block the visibility of other programs, and you can also move them anywhere around your desktop.
The program's user interface is intuitive and comfortable, and it allows you to manage your notes, search for them, and manage a recycle bin. You can click on the "New Desktop Note" button at any time to create a new note in a separate window. When adding a new note, besides its text, you can define the font, size, effects, and text color, all through a standard font dialog. In addition, you can also configure the background color and the transparency level, decide whether to use a gradient effect or not in the background, and even attach a file to the note.
Back in the main window, there is a list of all your currently added notes. You can easily edit or delete any of them, and select which ones to show on your desktop and which not. If you happen to have many notes, you can use the Search panel to locate a specific one quickly. Finally, the "Recycle Bin" section is a repository of all your previously deleted notes. From here you can restore them or delete them for good.
In short, Efficient Sticky Notes Pro may well be the right solution for you if you happen to be one of those people who use to write down every important thing in small pieces of paper that get lost very easily.
