“Scheduler” is a bit fuzzy. I know that @kgoderis is interested to introduce CalDAV integration to the rule engine, so that calenders can be used for scheduled actions. Wrt a “timetable” widget or anything like this within UIs themselves, I am not aware of any activities.
No, I cannot even recall a concrete bug report on this. And bugs are fixed once someone provides a PR with a fix - so it highly depends on the community.
[quote=“danielwalters86”] is there any documentation on how to use the javascript API in the new rules engine?

No, unfortunately not yet. This might also slightly change once the jsr233 stuff is merged, for which we are getting closer. Docs and examples will then follow.
