Sync Keyboard layouts
I have had to get new computers and switch to new ones a lot lately. My settings never sync to the new machines and I always have to remake all my keyboard shortcuts. Keyboard shortcuts should be attached to my CC account not the app on the computer. That way we can download our keyboard or workspace layouts when we upgrade gear or have to restore apps.

Another option is to put your keyboard preferences file on a USB drive (Documents/Adobe/"profile"/Mac - to find on Mac) but being able to sync over the cloud automatically without having to do anything would definitely be a welcomed feature.

The shortcuts are assigned to your account, not to your program. I have just yesterday synced my shortcuts etc. between my programmes. However! You have to do it manually, there is no auto-sync.
Check this out: File - "Your E-Mail Adress" - Sync settings now
Also check the "Sync settings" options in the preference menu.
