What problem does this feature solve?

When I select an effect or color from the taskbar tray menu, only the instance is changed, other instances cannot be changed.

How should this be implemented in your opinion?

I think there should be a sync button in the menu in the taskbar tray or a button to select each instance individually, then select the effect, or the effect can be applied to each instance, or all instances.

Are you willing to work on this yourself?

I'm ready but need professional help from you..
