Fish: Better looking prompt
- Prompt char being '>' instead of '$' Yes, just for the sake of having a little `~>` in my homedir :D - Different color for the base dir in the prompt pwd section - Right prompt of user@hostname and time I've had this prompt for like MONTHS and this was sitting in my uncommitted changes since then, lol.

# internet articles, terminal programs, and prompt

|

|

# - print user@hostname in right prompt (see fish_right_prompt)
