I noticed that if you jump between tabs in the new Theorytab (e.g. from Chorus -> Info -> Chorus), it will load an additional video everytime, without removing the first one. So if you jump back to Chorus for a third time, it will have loaded three videos underneath each other. This becomes extra annoying if you’re playing the song/video, as you will have multiple videos, but you can’t stop the one that is playing.
Just thought I’d let you know. Loving the new Hooktheory otherwise!
