iTunes has two options that control how it behaves when you add new media. Under Edit > Preferences > Advanced look at the options for Keep... and Copy... and make choices that suit your needs. You can also hold down shift as you start iTunes to get an option to choose or create a library. You can create your entire library on the external drive, move the media inside the media folder before adding to iTunes, and then no extra copies are created.
With iTunes 11 you can restore much of the look & feel of the previous version with these shortcuts:
- Ctrl+B to turn on the menu bar
- Ctrl+S to turn on the sidebar
- Ctrl+/ to turn on the status bar
- Click the magnifying glass top right and untick Search Entire Library to restore the old search behaviour
- Use View > Hide <Media Kind> in the cloud or Edit > Preferences > Store anduntick Show iTunes in the cloud purchases to hide the cloud items. The second method eliminates the cloud status column (and may let iTunes start up more quickly)
Should you feel the need to roll back to iTunes 10.7 first download a copy of the 32 bit installer or 64 bit installer as appropriate, uninstall iTunes and suppporting software, i.e. Apple Application Support & Apple Mobile Device Support. Reboot. Restore the pre-upgrade version of your library database as per the diagram below, then install iTunes 10.7.
See iTunes Folder Watch for a tool to scan the media folder and catch up with any changes made since the backup file was created.
If iTunes has "lost" data during the upgrade you can also use the technique above to try to get it to upgrade the database again, without rolling back the application to iTunes 10.7. This is usually successful.
