I hope these Vista features stay in Windows 7, which make small but positively significant differences to the user experience.
1 Bite-sized Breadcrumbs– Easier to navigate than the previous Windows explorer tree view
2 Hiding the menu (File, Edit, View, Tools..) and showing only the most relevant menu items highlights simplicity for the average user.
3 Favorite Links (option of adding your own folders)
4 Extra Large Icons (ideal eye candy for image and magazines- could be the default display option for multimedia folders)
Easy Keyboard Navigation (being a heavy keyboard user, I like these to be added)
5 Keyboard shortcut Alt+UP (more intuitve than backspace)
6 When going back a level in the explorer, focus remains on the file/folder where you started from.
7 To rename a file, pressing F2 highlights only the name and does not include the extension (nice!)
8 The brain-friendly menu system aka the ribbon should extend its presence to native Windows applications (like Movie Maker).
