Add an "archive binge" mode for scrolling

Most of the stuff I do on Discord involves only the most recent messages, and just scrolling up a screen or two at most. But sometimes I need to go further back, either because I'm looking for something specific or because I want to look at a lot of stuff from that channel's history. Unfortunately, the scrolling system isn't great for that sort of thing, as it has to stop occasionally to load new content and seems to occasionally jump back to the bottom when a new message is posted or for no reason I can discrern. The feature I'm suggesting is an "archive binge mode", which preloads messages for infinite scrolling before you reach the top of the currently loaded space, doesn't have a scroll bar (since it's kind of meaningless for infinite scrolling), and doesn't jump back to present unless you return to normal mode.
