My main problem with proportional fonts is not alignment (I don't really do that beyond the indentation) but symbols. Most proportional symbols, especially thin ones like dots, colons or the vertical 'or' bar, get too packed in between letters and can be hard to see. Since reading code with precision and ease is the most important trait I ask of my programming fonts, proportional fonts are out. But I'm open to suggestions about one that works.
