I enjoy using the predefined intervals. The crontab time syntax is great if you are used to it, but it’s not the best user experience.
What I’d like to be improved in the current predefined intervals feature is to support timezones other than UTC, and add more intervals to cover common scenarios.
Mock up of custom timezones, append timezone just like in crontab time syntax:
@midnight Australia/Melbourne
equivalent to 0 0 * * * Australia/Melbourne
Some of the examples at the bottom of the documentation could be predefined, I think workdays is a common scenario:
@weekdaily
equivalent to 0 0 * * 1-5
