Are there any keyboards that *just* have emojis and an IME switcher?

[Android Central Question]

I'm just curious because I use Hacker's Keyboard, and I wanna be able to quickly type emojis.

I don't want to navigate through another keyboard's symbol menu just to type a few smileys. I want to be able to swap input methods, emote, swap back, and keep typing with hardly any delay.

If anybody knows of an alternative, like a widget that lets you find and copy emojis, or a floating emoji picker app, I'd be okay with that too. I've been searching the play store for days with no results.
