Create and run cronjobs within the manager.
The CronManager for MODX makes it possible to execute snippets by the crontab of the server. By using the manager of MODX Revolution you can simply add new snippets to the cron list.
Using snippets for your cron management also requires properties and you can add properties manually by setting up key value pairs but also with a propertyset (name).
MODX Package Management
