Idea Summary
User should be able to select a simple time picker as field type. Basic configuration options should be either AM/PM or 24 Hour Clock. User should be able to select minute increments (i.e. 15, 30..) and limit hours, i.e. (9AM - 12PM).
More advanced options would be ability to select multiple times and those times be stored as a simple delimited list. I have a some ideas how this should look, get in touch for more info post.ethan@gmail.com
Use Case
Selecting times, such as what time each day would you like us to send you a reminder?
Preferred Solution (Optional)
Just select time select as field type, set some options and that's it. LOW CODE!
