I wonder what your thoughts are on showing flymake diagnostics in the
minibuffer after a timeout, similarly to how flycheck does it, or how
https://github.com/akash-akya/emacs-flymake-cursor seems to do.
My thoughts are that this is not so simple* to implement as adding a
function to the overlay keymap (hence the existence of flymake-cursor)
and thus shouldn't be left to the user if it is deemed a worthy
feature; and that it would be nice to have as a built-in feature
instead of having it in a third party package since there are more
than two forks of flymake-cursor already and I'm happy to avoid MELPA.
Would you consider incorporating this functionality in flymake?
and using the `eldoc-documentation-function' to display the errors.
