Re: Font selection, please consider making the fixed-width font configurable as well. This Consolas nonsense is turrible. Mostly because the 1 and l are so easily confused, it almost feels deliberate.
(It’s worst when they’re seen in isolation — side-by-side they look different, but an l viewed all by itself could easily be either glyph. “What command did you run?” ls. “And how long did it take to execute?” Less than 1s. “Well I would hope ls executes in under 1s!”)
