I used variations of the same homecooked bash prompt ever since my FreeBSD days 25 years ago, up until Parrotsec made me realize that a prompt doesn't have to be confined to one line.
So now I use:
username@host:/full/path #
:
...with a bunch of colors and special characters to make it more readable at a glance. That colon represents the input line.
To conserve some space I only used last part of CWD before, but now that it's multiline I can use the full path, making it easier when I need to copy-paste an scp-friendly path, as I'm usually working across a bunch of different usernames and hosts.
