Having used both the Fantasy & Sci-Fi Players for well over 12 months now, and being a SuperSyrin Subscriber (and integrated Syrinscape into Fantasy Grounds via the DOE: Sound Extension) what I’d like to see is a Button/Option to display the list of “Uninstalled” Soundsets. This would be placed with the other four Soundset-List Buttons in the top left-hand corner of the interface (ie with the “All Soundsets”, “Purchased”, “Unpurchased”, and “Installed” Buttons).
This would be way more convenient than having to scroll through the 225 (as as 2-Jun-2018) Fantasy Soundsets and the 106 Sci-Fi Soundsets.
And speaking of the 106 Sci-Fi Soundsets - how many people are aware of the 107th Soundset which is an exact duplicate of another Soundset? I’m talking about the “Absalom Station” Soundset which is a duplicate of the “IAS Absalom Station” Soundset - I suggest it is removed, as it adds nothing to Syrinscape that is not already there.
And finally - bring back the “Ninja” Soundset. That one was a lot of fun (even if it was only an April Fool’s joke).
Just my $0.02 worth 
Cheers
