I start a draft comment, then go back up to the top search bar search to find next comment I want to quote, hit quote again, and it pops into that same draft comment box and just continue for every quote after that.
For me the functionality is great. (Using safari or chrome) There’s no “scrolling back up” as my text box floats at the bottom half of the screen and stays wherever I am in the thread. So I can select multiple quotes without moving away from the post I am quoting. For example:
Literally just double clicked on each word in your post followed by clicking the quote button that appeared next to the word.
