The diffs that differential includes in email would be more readable with two "tweaks"
- Fixed width fonts
- Red/blue colors for +/- lines
This might be hard, idk (it is a jump to HTML emails). It would be good to understand how hard it is. Numerous people here have even been so bold as to say, "I like phab, but I need better diffs in email, and will code it myself if you show me the code...how hard could it be" LOL.
