Schedule Helper Feature Requests - UI Granularity, Reloading

[SirNate0]

As is, creating a schedule with the UI is not particularly usable for anything other than very broad schedules that match half-hour intervals (HH::00 or HH:30). Internally, though, the schedules are saved with at least second granularity. I was attempting to create a schedule that needs to start at 40 after, but there was no way to do this from the UI.

Instead, I had two options:

1. (Re)Create the schedule in YAML. This was more frustrating than necessary, as the layout of the schedule in the .storage/schedule file is json with a slightly different format than the YAML (shown at https://www.home-assistant.io/integrations/schedule/). Since JSON is generally (always?) valid YAML, simply running it through a site like yamllint.com is enough to do most of the reformatting, though some manual changes were still required. Unfortunately with this option the schedule cannot be edited in the UI, and nor is it even displayed read-only.
2. Edit the (seemingly undocumented) file .storage/schedule with the times that I would prefer rather than the half-hour increments. However there seems to be no way to force a reload of this file. While Schedule: Reload sounds like it should reload it, it does not. Same for the Developer Tools > YAML > YAML configuration reloading > SCHEDULE button. Seemingly the only way to get it to reload the file is to restart home assistant.

So, the feature requests:

1. Allow finer control of schedule event timing in the UI. At least 5 minute granularity, I would say. Either directly from the week view or as an edit option once a calendar event is selected (similar to how Google calendars works). Alternatively/Additionally, allow editing the UI schedules as YAML, similarly to how Automations can be edited as YAML or in the UI.
2. Provide a way to reload the .storage/schedule file as well, e.g. through the Schedule: Reload service.
3. Display the read-only YAML schedules in the UI, even if they are not editable.
