Not so much _pimping your existing shell_, but I'd like to give a
shout-out for `xonsh` (which I maintain).

It's a python shell - think IPython, but with first-class support for
running commands and passing pipes and arguments back-and-forth to the
python environment.

for dctrl in pg`**/debian/control`:
    head -n1 @(dctrl.parent / "changelog")
    sv = $(grep-dctrl -n -s Standards-Version . @(dctrl)).strip()
    if sv != "4.5.0":
        print(f"old s-v {sv}")

It's still admittedly a bit rough round the edges sometimes, and being
python there is a memory and performance penalty compared to
bash/zsh/fish/whatever, but I find being able to do flow control and
string manipulation without shell arcana is very useful (and to answer
the original question, the prompt and footer is fully customisable
either with builtin placeholders or the output of arbitrary python
