(you should increase the version number in the future, even if it's a very minor thing, people won't be automatically getting this update because it thinks they're up to date. just do something like 0.5.1)
I'm obviously going to be in the vast minority in this particular thread (which is fine--it's okay to not agree with the majority consensus), but I don't think it's a net positive to add emoticons/emoji/whatever you want to call them. I'm fine with them and even use them in small amounts, but they get overused and don't add to conversation much of the time. And I sure as hell don't want to have to see gifs everywhere.
fair, but i havent even seen them around at all really. this thread is not at all representative of the majority of people, people are trying it out for fun in this thread. if anything people are partial to ¯\_(ツ)_/¯ and thats pretty much it. this script only has 25 downloads. you have nothing to worry about.
i have only tested these on desktop, i have no idea if they work on mobile. i didnt even know ios could have userscripts? i thought it was only android. also, are you referring to this emoticon: ༼ つ ◕_◕ ༽つ?
edit: the script works on android, idk about ios yet
