It would be great to be able to choose the font so that I can use a fixed-width font in Obsidian. This makes writing in markdown much easier.
I am a programmer, and thus the natural attraction to Obsidian (I absolutely love it).
From this perspective, having a fixed width font is valuable, especially since I intend to use Obsidian to write documentation for my github projects; the graph view is very nice for this also.
