What we need A grid view where the columns are a resource (channel, room, stage), the rows are time slots, and each record is a block in its column. The top of a block is its start time and its height is its length.

Our use case For live surgery at our congress, we run several channels at the same time. We want an overview with one column per channel and the day's time down the left, so it's clear what is live where at any moment and where there are gaps or overlaps. Today we can only show this as a list or a table. That works, but you can't see at a glance what runs in parallel.
Why it's useful beyond our case The same layout fits room and stage planning, staff rosters, equipment bookings and booth or meeting-slot planning: anything where several resources are scheduled side by side over a day.
Nice to have
- Configurable time step (for example 5, 15 or 30 minutes) and day range
