FNCTreeView - Node visibility

It would be nice to have the possibility to hide/show nodes.
For example:

I have a treeview with around 150 Nodes with different multi-level parent nodes. When I want to drag & drop a child node to another parent, its painful for the user to scroll to the wanted parent node with all the childs. In this situation it would makes sense to hide all other child nodes, because its easier to find the new parent node. Currently I have to remove all child nodes (and the depending data objects) and recreate them after the drop was done.

Furthermore for filtering via TEdit it would be nice to show only the nodes which matches the filter and hide the other nodes.

Right now, controlling visibility is not possible, but we'll write this down and see what is possible. Thanks for the feedback.
