Is it possible (not too cumbersome) to add a room update( status, name, beds) feature using maybe a button in the row header ( or click) ?
You can activate a context menu for the Scheduler row headers: https://doc.daypilot.org/scheduler/row-header-context-menu/
Or you can add an action icon to the header: https://doc.daypilot.org/scheduler/row-header-active-areas/
The Scheduler can also handle a simple click: https://doc.daypilot.org/scheduler/row-header-click/
You can use one of these methods to open a modal dialog and update the room details.
