don't forget:  You propagate all settings across the layout. Which makes no sense at all. It spoils all benefits from having different layouts for different computer setups (except one: the positioning of the windows across available screens).

well, that's not logic at all.

I chose a simple example to simplify the reproduction of the problem on your side.

But let's look at it like this:

You provide me with the possibility to change background color and font color in a cluster chart. 

When I change it for asset A, it doesn't change for the other assets that I also have open windows for in my Layout A.

(here:  not at all "users want the same Colors for all.."

But in my other layout B all my assets, not only the asset A (exp ES)  has changed settings for the cluster.

Please put yourself in a user's position. This is no request about "beauty" or personal preferences.

It is essential, that READABILITY is guaranteed.  That's what all your color and option settings are for.

So from a usability point of view it is non-sense that ALL my charts in the laptop layout changed while on my desktop setup nothing has changed except the one asset chart that I explicitly have changed manually.
