How are multiple marriages and half-siblings displayed?

[LukeScania]

We are currently evaluating Topola as a follow-up solution for a current genealogy tree which has been developed 9 years ago. I have a few questions about specific use-cases:

1. How are multiple marriages/divorces displayed?
2. How are half-siblings displayed?

In our current solution we have tabs for alternative spouses. half siblings are displayed next to each other without being connected.

Here is an example:

Johannes Bernoulli had two wives. He had children in both marriages.
