Is there any way to save state of wunderbaum?

[gioisco]

What is the best way to cache the state of wunderbaum (nodes selected, lazy nodes already loaded) to allow it to survive a page refresh?

For reference:
persistence is one of the few features that was not ported from Fancytree ext-persist (source)

[gioisco]

Oh no. Maybe I should use Fancytree for this feature :(
