Spec synchronization

[Mars85]

Hello,

I'm searching an addon which helps me keeping the actionbars synced for dualspec. I know there are button saving/loading addons, but I don't want some "magic" where I can't know what is changed by the addon (such function in the same addon would be great, but I mainly need the check).

I basicly need two functions (two addons would also be okay):
- Checking if all spells/abilities are placed somewhere on the actionbars, telling me which aren't (used several keywords and didn't find any addon for that )
- Telling me which actionbar buttons aren't in sync between the specs (like "bar 1 button 1: Roll vs. Empty")

Regards,
Mars
