As its name implies, this program is an electronic version of the popular Post-It sheets that many of us use to take notes and write reminders. The application is really simple to use. You only need to launch it and click on the "New note" button to create a new note. You can choose between 14 different colors, so it is possible to create your own color code for your notes of different significance and priority. If you want to "stick" a note to your desktop, i.e., to make it permanently visible, you only need to click on the pin image at the upper right corner of the note. To delete a note, you need to right-click on it, which opens up a pop-up menu, and choose the "Delete" option.
Apparently, the program has no limitations regarding the amount of words you can write on one note; nevertheless, you may want to keep them short so you can read them easily.
The free version of the program has some limitations. One of them is that you can keep only five notes at a time. Also, according to the manufacturer, it lacks some advanced features (although they don't mention which ones). There is also a Pro edition, which you can purchase from the developer's site.
