Grouping events by entity
The label at the top of the timeline changes to indicate the group that is currently displayed.
If an entity has a birth or death, these will be marked on the timeline when that group is selected.
Comparison to Desktop App
This provides a similar function to the Group By option in the Desktop app. The main difference is that the iPad shows only a single group at a time, whereas the Desktop version stacks multiple groups on top of each other.
This is because the limited screen size on iPad makes it difficult to scroll and navigate between groups, so switching between them via the side bar makes navigation much faster and easier.
