show docstring in a separate column

[a13]

I would like to emulate something similar to ivy-rich by setting

which-key-show-docstrings t`

which-key-max-display-columns 1

and

which-key-max-description-length nil

it looks ok except the docstring is separated from the command name by a space, which isn't perfect tmo

Is it possible to make the delimiter size dynamic depending on the maximum command length on a current page?
