There are lots of folks here for which the shell interface is usefull, but difficult to use. Using colors and graphics can be super helpful for folks with dyslexia, along with asymmetric fonts (thing I learned this year: comic sans scores incredibly well as a font for people with dyslexia). So don't poke fun.

I don't have that problem, but I don't see any problem including redundancy. I have come to like Powerline-hs's git support because even if I only half-glimpse a window I immediately know the status of the repo from it just by the colors. I don't see why I wouldn't want to maximize the channels of information coming back to me.
