add more emoticons or customization options

I haven't seen a way to do this yet, but I find the standard emoticons that are offered to be very bad and lacking in terms of the number of different options.
For instance, literally nobody I know uses ":-D", it's always ":D" which makes this function basically useless for me personally because it seems completely unnatural.

But those are quick to type out yourself, I think it's much more important to add ones that you can't easily recreate on your own like "( ͡° ͜ʖ ͡°)" or better, just give people the option to add and customize emoticons themselves.

I'm aware that you can add them to your clipboard and assign shortcuts, but I would personally prefer having them in the same tab as the standard emoticons, that would be much more convenient and logical in my opinion.
