Classic Explorer Treeview

This mod changes the Explorer Treeview (otherwise known as Folder Pane or Navigation Pane) to look more classic. It draws it's own Folder Band with a functional X button. If you are using OpenShell, then you need to set the correct settings for Classic Explorer in the Navigation Pane tab: Vista style and Tree item spacing 0.

This mod supports the Classic and Basic (non DWM) themes, others may work but aren't supported.

If the mod is to be disabled, it's recommended not to use file explorer windows that were opened prior to disabling it, as it may lead to undefined behaviour.
