Big karaoke fan, so thanks for doing this. I'm processing a first test song as I write. The pitch scoring sounds really interesting as both a competitive and maybe also a training tool.

A couple of immediate small pieces of feedback:

* The colour scheme on the queue/nn% buttons is really low contrast - white on pale yellow is very hard to read

* the 'models' button (bottom left) - I assumed this would give me details about which models are available, and the sizes, but instead deleted the downloaded models without warning. Maybe add a 'are you sure you want to...' check?

Processed Kenny Rogers' The Gambler perfectly - took out the lead vocal but left the backing vocals.

hey, thanks for the feedback, both noted!
