I don’t have any options for you but make sure you get one that doesn’t use battery when not in use. It’s really annoying replacing those little coin batteries all the time even though you only use it like .001% of the time

I would say solely doing this would be unpopular and I wouldn’t be for it.

I could see it working. Properties:

Assign each emoji an up/downvote and keep the current system. Hitting an emoji also does one of these.

Have a separate bar for emojis that is collapsed by default

Make emojis optional so you can still up/downvote
