Hey, I see how you may have wanted to create one but emojis work well because the emoji picker pops up on cmnd + spacebar wherever I want. How are you planning on navigating this?
This is so cool. I like it. You've got a couple of issues with your layout, though. Not all emojis get loaded. First batch of emojis doesn't trigger scrollbar on certain screen sizes which makes it impossible to activate infinite scroll and call next batch of emojis. Maybe add a LOAD MORe sort of button. The COPY button doesn't work for me.
The main functionality is neat, though, so I'm supporting it.
