Feature request: incremental unhide of nodes

[fieldrabbit21]

thank you for your plugin!

I like to use the canvas for story telling.

For this I like to start with showing one section of the canvas, and as the story progresses new parts of the canvas are shown. At the end the end, the full canvas is visible.

so, my request is, can you make it so that I can progressively unhide parts of the canvas?
