Proposal for a new treeview style (1 Viewer)

[doskabouter]

I've done some experimenting, and as far as I know, there isn't a treeview like control with the following properties:
no checkbox/radiobuttons needed
+ and - button before each treeitem that has children
higlight the caption of the selected item.

the first can be done by selecting the default, but then I don't get the 3rd (which I do get with the SingleMarkableTreeViewStyle)

The 2nd is a nice to have...

Is anyone willing to create one?

Thanks in advance!

Edit: and the possibility to add a thumb image...
