Sort/filter free rooms

[Obito1903]

It would be great if we were able to filter free rooms by number of seats or whether they are currently free or not.

Another nice feature would be to be able to see if a room is free at a different time.

A way to filter the rooms by seats and by computer presence seems to me to be a good idea.

The free room system is currently not optimized.

Being deduced from the schedules, this calculation is done at each request, which is not very good.
We plan to modify this by putting this calculation in our synchronization service :

This will be done in the next update.

On this occasion, an improvement of the ui and the functionalities will be made.
