tl;dr
"It currently does not do anything to facilitate working on multiple monitors, as in my current setup I'm only using a single monitor for my Linux machine."
I'm the author, and that's still true. I'd be open to addressing it, but it's not currently a priority for me to work on. I'm moving soon - if my new office gives me space for a second monitor that may change ;)
Two monitor life is a good life but it’s the part of my i3 config that’s most annoying. I guess idk exactly what I want but I know I don’t want to fiddle and fight with my i3 config lol
