As title says - this issue has been plagueing this amazing addon for years now.
As you can see below - 2 top windows were made on day 1 of setting up fresh details options. I changed everything, font, sizes, layout, etc.

Fast forward few days later, same exact logic - i create 2 more windows via Window Control -> Create window
Except this time the new window act like Details was just installed fresh. No idea why.

Is this a bug or is there a way to force these windows to inherit the "parent" window settings?

Example:

Skins->Apply to All Windows button, when you have selected one of the other ones in the dropdown at the bottom right

Thank you! That worked! Didnt know about that feature.
Its very weird though how first time i created 2nd window it took the settings of 1st one, then later that stopped.
Something wonky is going on.
Anyways, problem fixed, thanks!
