Overview of lessons currently taking place
Along the lines of #119, we could implement an overview of al llessons currently taking place. Re-using the timetable templates, we render a new kind of plan where all teachers or rooms or groups are columns listing the lessons on the current day, with the current lesson row highlighted.
This can either be an alternative approach to #119 or exist additionally. #119 would be an intelligent feature (AlekSIS suggesting a free room), while this approach here gives an overview of all rooms as a visual aid to determine a free room manually.
The implementation should be rather simple and could help get this feature into %"2021.06 — "Bruner"" if #119 as an interactive smart suggestion is out of scope.
