I like syncing. But I'd like to be able to turn it off for certain things.
I have a 27" iMac with a second monitor (460 square inches, combined, if I've done the math right). I also have a 13" Macbook Air (75 square inches) and a 10" Asus Netbook.
My layouts that I create and save on the iMac simply don't work on the much smaller screen, so I've created other layouts. The problem is, whatever layouts I save to the toolbar sync to the other systems. If I drag a small layout, that syncs to the iMac. If I create a large one, that syncs to the small one. If the toolbar shortcuts could be NOT synced, I'd find that very useful.
Ditto for the preference in font size.
