I'm talking about not only how to keep data but also how efficiently to manipulate with it.

I found new Python library - [awkward array](https://github.com/DryRun/awkward-array). It can create arrays with nested arrays of different length. Such arrays can be handled by NumPy and Numba libraries. But also...

Unfortunately Blender developers does not care too much about adding new features into custom node tree.

Responsible functions https://github.com/nortikin/sverchok/blob/db0615e5d3002f810fbed684b0801038de153fc9/utils/modules/polygon_utils.py#L318-L337 https://github.com/nortikin/sverchok/blob/db0615e5d3002f810fbed684b0801038de153fc9/utils/modules/polygon_utils.py#L432-L449

I don't think this will hurt anybody. )) But such documentation should not suggest that anything in Sverchok will not be unchanged between the releases. So you can use something...

Nice. Is it possible to add main page in `md` format to join all links to API there? It would be just more convenient to edit it in master than...

Or we can make it simpler. We have section for developers in the user documentation. So we can add extra page for links to the API documentation from there.

Tested it out ) - http://nortikin.github.io/sverchok/apidocs/sverchok/node_tree.html

I just made a test with Python list and NumPy array (only vertices) and it appeared that with NumPy the node works quite slower (in both node execution and drawing)....

It seems does not have too much choice. It uses the same Blender API. https://github.com/nortikin/sverchok/blob/015081d94bcf3f45b9e48bc8ca30354d67ba3598/nodes/viz/viewer_draw_mk4.py#L188
