Thank you for your message.
Regarding Fleet View, I will make an adjustment so that it is integrated as an optional dependency.
I have re-added 'Visible Planets in Space' so that the Shattered Planet backdrop is displayed again. With the 'Use base game platform backdrops if available' option enabled, only that backdrop should be modified by 'Visible Planets in Space'. Please check if this setting is enabled on your end.
Ideally, everything should be compatible with each other. If not, could you please explain what isn’t compatible in more detail?
That aside, I'm currently developing my own solution and will switch to it as soon as it's ready.
