Exclude disk from Eject All
I'd love to see a tab under preferences where I could choose disks to ignore when performing the Eject All. An interface like the "Exclude these items from backups:" from Time Machine would be perfect.
Like a lot of people, I have an SDXC flash card in my MacBook Pro all the time. When I leave work, I'd love to be able to eject everything except it with a single click.
