Aggregate number of missing people over slots
Description
Relating to the 'traffic light warning for stores' feature: A store with 1 person missing tomorrow (but the entire week filled otherwise) displays the same red that an entirely empty week would.
For overview purposes, showing "how many slots are empty in the next 3/5/however many days" could help a lot.
(Describe the problem and the affected use cases)
Impact
Better overview for BIEB and above. (Which users / user roles are affected? Why is it important to solve this problem?)
Proposal
Aggregate number of missing people over slots.
Let this number be shown inside of the coloured badge (like we have it with bells). (How do you propose to solve the problem?)
