[FR]: Treeview main node - Context menu option - Collapse/Expand nodes

[pipiscrew]

On the treeview main node, when user right click then node, on the mouse context menu, should be added 2 more options

-Collapse
-Expand

which doing the needed on children folder nodes.

You can expand/collapse by mousel double-click or with keyboard arrows. I believe it is enough for now. If more people request this, I will implement.

imagine that I have expanded 20 folders under the main node, there is no option to collapse with a click.
