Mind Maps - Groups and Focus Mode

It would be amazing if we could group connected notes/nodes and give each group a name so that you can see at a glance what that cluster relates to. Once grouped, a Focus mode could highlight that cluster while dimming everything else. When a mind map gets large and cumbersome, being able to zoom in on one train of thought without losing the bigger picture would be really useful. It’d also help if each group could have an anchor note where clicking the group would centre the map on that note that the ideas and train of thought has sprung from.
