Recursive collapse support

[khasanshadiyarov]

Man, really good extension, I think you use markmap.js or similar package, can you please add support for recursive collapse, so for example when I press Ctrl and click to collapse a node, all its nodes are being collapsed too.

You can find an example of my words reviewing the Markmap extension.

P.s. I am not using Markmap extension, bc youth is much convenient to use.

If you click the circle symbol of node, you can collapse a node.
