Reddit Sidebar Toggle Button

does exactly what it claims. I use it on old.reddit.com with RES

Finally! :) The button hovers very discreetly on the bottom right, doesn't interfere, but is always there, when needed – thank you! /EDIT Just found out it only works for me, if I opt out of the new reddit permanently...

Really wish it worked with old.reddit.

This is perfect for when I have pinned windows on my laptop, and Reddit's stupid sidebars intrude on the entire page, leaving comments going vertical one letter at a t i m e. Thanks!
