I would love to have planner functionality on a day level. I believe this can be achieved in 2 ways:
drill down planner to 1 day view (1week on screen)
add sum of hours visible in Workload balancer (at the top or at the bottom)
Its a struggle to understand how many hours in total there are available in the team on a given day. For tasks that need to be handled urgently it is essential to quickly understand if the team at all has capacity and if yes which resource exactly. Latter is somehow handled by Workload balancer, but data contained there is nowhere in the system summarized per day.
Its not even easily available via API, which could a workaround.
