I'm just not a fan to be honest. I think find it distracting. I found myself wanting to resize it out of the way. It felt like the content in the drawer and the content in my feed were mutually exclusive, which meant my attention shifted from either, and when one needed my attention, the other was in the way. That said, I really disliked the drawer in nostrudel and was happy when he removed it as well. I think I just wanted one thing in focus at a time. For example, I use 4 monitors at my workstation, all windows are maximized in them at all times. If something needs my attention it has it exclusively, then it goes away.
