Faster loading Artwork on the movie wall
Artwork for the library should be downloaded and stored locally on the Zappiti rather than loaded from Zappiti Server each time.
That way artwork for larger libraries would load much faster on the video wall rather than lagging so much - other similar player seem to be able to do this with the slow loading Zappiti currently has
Sadly when running Zappiti Server on a local docker compatible NAS its still still slow to load the artwork on the movie wall and does so each time at boot.
Isn't this what happens when you manage your collection locally instead of cloud-based? I'm pretty sure you have this option already.
Look into what local server does.
