I installed ov from homebrew on OSX 14.2.1, did:

ov --follow-name --multi-color "ERROR,INFO,WARN,DEBUG,^2024-.{19},\[.*]" --wrap corda.log

and didn't get wrapping or the color highlighting, which I expected.

And I then noticed an error:

dickon.reed@LDNM-RP94MJ9T71 logs % ov   --follow-name --multi-color "ERROR,INFO,WARN,DEBUG,^2024-.{19},\[.*]" --wrap corda.log
failed to read config file: Config File "config" Not Found in "[/Users/dickon.reed/.config/ov]"

and figured nevermind, I don't need a config file yet.

If I create an empty config file at ~/.config/ov/config.yaml the command line options work as expected. Initially I tried to make an empty file ~/.config/ov which of course didn't work.
