Quote from TomberRaven only provides separate settings in the per-character profile for a subset of it functions. This is described in the description near the end in a section captioned "Multiple Characters". The only per-character settings really are bar groups, conditions, and Button Facade settings. Also, using Link Settings many of the bar group settings are by default shared (if these are what you are referring to then try turning off Link Settings in each bar group and see if that helps). This is all by design. Please let me know if there are specific settings that you don't want to share between characters and I'll let you know if there is a way to accomplish that.
Hum, ok, I didn't see this point. But why make it working like that ? If I want a shared profile, I use the "Default" Ace3 profile for my characters, and if I want change a little things for a specific char, I just use a "Char - Realms" profile and copy from Default and change my settings. In my case, I don't want to put at the same place my buff / debuff / alert for my rogue and my priest for example, and it's now impossible to do. Perhaps you shoud add an option to control the behavoir of profiles, it's a shame because Raven is a very promising addon (and in a great way to replace EBB2.0 + Classtimer + some colddown addon).
