When a file has more than six flow starting points, then not all of those points are shown in the presentation sidebar. It is possible to resize the section “Flows” to accomodate more items, but there is no hint that any items are not shown.
Problem:
If users are not aware that there are than six flow starting points, they will not think about resizing the section.
Possible solution A:
Either make section “Flows” scrollable and display a scroll bar
Possible solution B:
Increase the default size so that 6.5 items are shown - the haft displayed items will be an indicator, that there is more content than currently shown.
