Any plans to extend cut / copy function or search / filtering in Flatnav?

[rtpdho]

Hey,
we're using flatnav in a few projects and it's a nice package.
What we're (or our customers) missing are the cut / copy and the search / filter options of the default tree.

Are there any plans to extend the module with these features? (I don't exactly know how complicated it would be / what it would mean in development time).
Can we so anything to support the possible development of this new feature, whether financial or with man-power?

Thanks in advance,
David
