All's looking good here, @Roniscend! A few points:

• Can we fix the icon on the emoji key as it's off the key now

(Pixel 9)

• What are we doing for the clipboard key on the 123 keys? Are we leaving it or removing it? If we leave it, it should likely be between the comma and space bar for consistency. (feel free to make this change if we're keeping it)
• For the long hold option, we're not allowing the user to slide for an option as we do with alternate characters keys?

I'll take another look after the next commits!

@angrezichatterbox, checking in with you as well: Do we want this to be a slide as well? And what are your opinions on the clipboard key on the 123 keys?

I am fine with the clipboard key on 123 but I'm not sure if thats a good pattern to follow as it feels like a easter egg. Can we have a similar implementation to Gboard if possible on the force touch so that it feels more elegant. The alternate keys in this case could be more centered. This is what I felt @andrewtavis. The current implementation is good enough but it wouldn't be easily visible to the user.

Let's get these improvements in so that merging this finalizes this then 😊 Thanks for the review, @angrezichatterbox!
