Is it possible to see an overview of a week, with all appointments of all rooms?
Because we can only see the appointments of a week of 1 room, and not all rooms.
No, not as standard. The difficulty in providing this as a generic feature is screen space. An area could have tens or hundreds of rooms and displaying all rooms for all the days of the week is difficult.
You seem to have CSS turned off.
Please don't fill out this field.
But you do this on day view - rooms across the top and times down the side. How can we extend the times down the side to 7 days?
Well you could do it, but you'd have a lot of scrolling to get to the end of the week. You'd have to modify the code yourself: day_table_innerhtml() in functions_table.inc
