1. Drag to expand vertically
Having dozens of files to look through and not being able to expand the viewing area is cumbersome. Being able to drag the whole thing vertically would be a huge welcome.
2. Sort List Headers
'Nuff said
3. Search with realtime results
Is real useful when looking for specific file types like .FLV
4. Quicklook to preview selected files
Instead of having go back and forth with pages via the 'Display' button all the time, previewing files this way makes things a snap.
