For the last week or so I've been stuck using my laptop which is pretty good, but it only has one screen compared to my primary computer which has three monitors, so I'm missing having all of that space available to me. I then installed Manjaro with the i3 window manager, and I have to say it is fantastic for doing multiple tasks at once. Once you have memorised the keyboard shortcuts, it makes working with multiple windows at the same time on a 1080p screen easy. You can see everything side by side and if you want one window to be full screen for a short time, then you can press a keyboard shortcut, do what you want, and then disable the entire screen. If you've only ever used something like Gnome or KDE, I highly recommend you check it out. Even when I go back to my three monitors set up, I'm going to be sticking to i3. It makes you so much more productive.
