Hi,
Interesting to see that you have decided to go with cron syntax for scheduling. Not having used it before, I would love to see some natural language translation added - maybe these will help:
Check out what these guys have implemented in their system:

It’s funny, the top library will already be in use as a way to translate the existing CRON expressions to readable strings. I’m happy to implement some additional helpers to provide easier ways to do scheduling than CRON alone but figured CRON is what most things will be translated into anyways so we would start there. That said, adding easier ways to schedule things (similar to the UA scheduled endpoint syntax) might be handy.
