During my childhood, I lived across the street from a brewery. I suffered from chronic sinusitis for years, and no one understood the cause.
When I moved to a different part of town, the problem immediately stopped.
The same thing happened to one of my classmates who lived in the apartments next to me.
Honestly, I don't understand grids on a laptop. Probably, if you have a 27"+ monitor or two, you need this. For my 16" laptop, I use several Spaces (virtual screens) with several applications assigned to each of them. I took this from my fvwm/icewm days, and it is still the best way to manage small screen spaces for me.
