1. Allow admin to set the time zone, for example, AZ MST - USA. Then when admin is adding items such as sliders we do not have to convert the time each time we do a sale (which is often). This is time-consuming and not efficient.
2. Once time zone is set in place, allow for slider scheduling to go full range of sale, not per day. For example, our sale goes from 9/6/17 at 9 AM until 9/11/17 at 11:59 PM AZ MST. Admin should be able to select that exact time range and not have to make separate sliders for each range/day: First day of sale = 1 slider running from 9 AM to 11:59 PM, middle date range of sale = 1 slider from 9/7 - 9/11 from 00:00 to 11:59 PM and then I have to create a 3rd "filler" slider to run until the next sale begins a few hours later (see #3 feature request below).
3. Create a "Default" slider that runs 24/7 unless there is another specific slider during that time. You create 1 slider and select "Default" so that if nothing is specifically scheduled at that time, the system reverts back to this "default" slider so that the site is never without a slider if someone forgets to create a new sale slider manually.
