Something I haven't come to grips with is the odd glue entangling scenes and styles. In a scene (one is always 'in' a scene?), if I change a display mode (face style) SU takes it that I want to change the currently active named style, but no, I don't, I want to change the display, for the moment at least, just as I have indicated. Now you are likely thinking, there is that setting as to whether I want SU to 'help' me manage my scene / style settings ("warn of style changes when creating scenes") or just royally ignore what I want and do what it wants, with insufficient notice, in my view. It seems like if I say I don't want to make any changes to styles it instead ignores the scene changes I have made and attempted to save (usually regarding layer visibility).
I think this is how I believe SU is telling me it will act: Any change made to any setting able to be set in the scene manager will be interpreted as a desired change to that named scene active at the time. If instructed to let the user manage style changes, it will not prompt to save said style changes but will perform scene changes as may be requested at that time.
Sorry for my poor articulation... This is either a simple little whine or a lack of understanding, or more accurately, a whiny lack of understanding.
