Feature Request: Group links

[alkuzman]

Problem

For well-connected abstract concepts, e.g., concepts with many extensions and variants, the graph becomes cluttered with many overlapping links.

For example, let's say we have a concept with many extensions (concepts that have is a relation) and a handful of concepts that are part of the original concept. All these connections are children. They are visible but placed in a random order, making it hard to find all extensions.

Solution

Group all nodes connected to the central node with the same link (link label), put them in a container, and add only one link to the container instead of repeating the link for each node.

Moreover, this container can also state how many such nodes exist in total, and hide most of them. How many to show per container can be a settings property.

Bonus: containers can be unfolded individually to show more items.
