Let users trim long recordings to just desired vocab/phrase
I wanted to know how to pronounce 頂点 (ちょうてん). It's in the recording at https://rhinospike.com/audio_requests/aquaadragon/11822/, but every time I forget the pronunciation and want to hear it again, I don't want to waste 2 minutes clicking back and forth in that audio track trying to find the particular part it's in. Let me turn 頂点 into its own Japanese Audio Request type thing, and select just the part of the already-available track that contains this vocab. Then in the future when I search for 頂点, let me see both the recording with just that vocab, and also the original lengthy recording.
Once this basic functionality is implemented, you could make it even better with an option (when listening to the vocab pronunciation) to play the longer track with the vocab used in context.
