When viewing/editing Appointments or Events the already large box with even larger content also shows allot of white spaces which means that you see less in an overview because less details fit in these page layouts. This is cumbersome. Can the size of white spaces be reduced and also for the rest of the elements, is there a 'Compact' view similar to what you select in Salesforce Lightning which provides options for 'Compact' or 'Comfy' views. This will give a better picture of the detail. An option to increase the popup window size additionally might also help.
What is the underlying problem do you intend to solve with this idea?
See more at once, less scrolling more efficiency
How is the problem being addressed today, if at all?
No solution, users must scroll allot to see the content they need.
