qroneko is a scheduling utility which uses crontab as the backend. - crontab is a unix command to install, deinstall or list the table which contain scheduled commands. ( see detail cron/crontab manual. )

features and highlights:

• Smart "Cron Time" Setting.
• Lists expected execute time.
• Enables to edit crontab by text

All user's maintaining crontabs can be edited by superuser.

however, crontab of new other user cannot be created.

Lists expected execute time.

can be changed max number of list and max day from now (ex: max days 2 will be displayed 48 hours data from now).

Fairly smart, but not perfect.

Months and weeks expression can be changed literal or numeric.

I means...
  numeric : 1, 2, 3, ...
  literal : Jan, Feb, Mar, ...
