Preload channels in background

It would be nice if discord preloaded all of the channels in the current server that you are viewing in the background so that there is no delay when switching from channel to channel. Maybe start with most recently active and go down from there, and maybe set it to only be active on wifi by default to avoid using too much cell data for people on phones. This may already be a feature but from my brief testing it didn't seem to work like this.
