The one app is i3wm. People say tiling wm do not help boost productivity, but it certainly did for me -- or at least I think that it did. From hardware aspect (although it was never asked), I use a hhkb type-s with the hasu controller. You may think it's a small change, but the fact that you can remap the arrow keys to {h,j,k,l} also helps because you no longer need to stretch your arm to your arrow keys. It did cost a bit of money, but I'm happy that I have it. And aside from the arrow key remap, I also remapped other keys to help with basic functionalities.
