It's average, can be useful, but far from being perfect. They are without color in the window, but they appear yellow in my doc, so it's okay, there are approximately 80 emojis, and there are all about faces and 4 or 5 cats and ET faces. To be really useful, there should be more of them, and with more styles. There are so many existing emojis now! Also, the insert mode is not good, it copies the emoji in the clipboard. It would be easier and better to click, and to have it inserted directly, as other extensions do for letters.
