HEAD
- Optimized portfolio file list:
Also display header for empty directories and show empty message.
This should avoid confusion about a screen with many functions but no portfolio files.
- Optimized spacing for "Portfolio FileList" help link
- Optimized "Delete Directory" button:
- Moved button from above to below the list, right below the empty message (see above)
- Removed unnecessary variable
