smooth scrolling takes a fairly large toll on performance, and that's why twitch and youtube (when chat is fast) don't do smooth scrolling by default either. it's also especially hard to make transitions blend together when messages are of uneven length and are arriving on uneven intervals. i could consider adding an option like this, but it'll be low on the priority list

Actually Using like scrollIntoView api which is browser-built in function, I maked better performance than 'scrolltobottom' which is library functions

1. it's not really fair to compare to regular ytc, u have to compare hyperchat with smooth scrolling vs hyperchat without smooth scrolling
2. try scrolling up while the chat is moving. the problem with the scrollintoview api is that it tries to keep scrolling even when the user scrolls up. terminating scrollintoview on user scroll is not very straightforward as far as i know. if you can figure it out though, pls do make a pr, id be happy to merge it
