In one word: works! In more words, not only works, but it's also amazingly tiny, about twenty kilobyes in size (compare that to over 600 kB or even 4 MB of the most downloaded alternatives, that last one expanding to over 21 MB after installed!), and very minimalist. It could be improved with a better interface (the options just pile on each other in the pop-up bubble) and an option to enter custom strings and/or edit current available selections. Indeed, this should go to the top of the list!
