Hi Javier, I don't want to complain, but the new version looks really weird, see attachment. This happens only, if the output of crontab -l scrolls up the existing text. TERM is xterm-256color.
Not to mention that the comment line mode is not switched off, if the last line is a comment. This might be difficult to fix. I would recommend to kick out the highlighted comment lines as a default, and to make this feature optional. Regards Harri
