Windows 7 Explorer tree view expand

I miss the simplicity of the old windows explorer. That being said, the only way I know of to have some indication of which folders have sub-folders and which don't on Vista is as follows:

• go to Control Panel
• open Folder Options
• go to the View tab
• Under Advanced Settings and under Files and Folders
• there is a checkbox: Display simple folder view in Navigation pane. Uncheck it.

Now in your folder tree view, the folder nodes that that don't have any subfolders will have a straight line flowing down their left side whereas those folders with subfolders have a blank space (where the triangle would be) on their left side with dots above and below the blank space.

If you click on the arrow next to the folder or drive name, it opens with one click only. But indeed it's much smaller than clicking on the full name.
