Option to dim when used with Stage Manager and the desktop is not the active focus. #177
Description
Is your feature request related to a problem? Please describe.
When using Plash with a productivity tool in the background, or a calendar in the background, it can be distracting / feel crowded.
Describe the solution you'd like
An option to "dim" and monochrome the plash when in Stage Manager and the desktop is not the active, i.e. an application is in use.
Describe alternatives you've considered
Have not been able to think of any so far.
Additional context
macOS actually has a feature where it does something like this with widgets on the background. You can choose to show them but have them 'monochrome' when the desktop isn't active.
