why assets modifications like guiskin and prefabs are not subjects to save action?

Hi,

I find odd and dangerous that assets like guiskin, prefabs ( and I think materials) and the like are not subject to save protocole. If I change a setting, it's done, and if I quit unity it doesn't ask me if I want to save my changes. Saving warnings and action only seems to affect scenes.

Am I correct? am i missing something? am I the only one to feel uncomfortable with this?

thanks, for your insight,

Jean

Any asset (with the exception of scenes) which is edited in Unity is automatically saved when editing. This includes all prefabs, all custom ScriptableObject assets and Materials, PhysicMaterials, Custom Fonts, etc.

We are aware of the fact that this is not a perfect solution (which means we want to fix it eventually), but for now, this is how it is.
