Although it is a really small application, it has many features that many other competing applications don't have, like it supports Unicode, has both pop-up and floating list, and has a paste button (supporting Unicode was especially important to me, and this program does it without a problem). Also using this program is really easy with its forthright shortcuts like: Ctrl+Alt+Arrows for floating list and Ctrl+Alt+V for its pop-up to appear, which this latter can be customized too. Its floating list also has a drop-down button for the list to be really small when it is not needed at the time.
I tried many others (at least 6 other famous ones) and have chosen this one. It is effective and efficient.
