Current folder or path in portal title bar
The portal fences are great, but I tend to get lost in them. When navigating to a subfolder within a portal, the title bar text remains static. The only thing that changes is the folder icon, which becomes a clickable back arrow.

Here are a few additions I'd like to see in a future release:
- While navigating within a portal, the title bar shows the current folder name or path
- A button for jumping back to the top-level portal in 1 click.
- An option to have portals reset to the parent folder when the user navigates away from the desktop or after a certain period of time
- View settings propagate to all portal'ed subfolders.
