Problem Description / Use Case

The current calendar is rather cluttered when I have a few dozen presets. I have a big calendar for 10~ people, so they can check who is working when, all read-only. But the clutter from the presets + statistics is taking up a huge part of their screen, and it confuses them. I wish to turn it off.

Proposed Solution

To unclutter the view, I would love to be able to toggle on/off the statistics/presets for logged-in users. This toggle should appear on "manage presets" to toggle visibility on/off, and for the statistics, a toggle should be on "view settings".

This makes it possible that users who are logged in can easily view the calendar and their shifts, without receiving the clutter from a dozen presets and statistics.
