limitations:

- When you use the ``Post`` mode Sverchok/Blender expect Objects to be visible. If you want to "hide" the original Objects in the scene to avoid visual clutter, you can place them into a Collection and hide the collection. This is a current Blender API limitation.
- Another method to work with objects - select wireframe mode and hide objects in Render by buttons:
