Suggestion to lower the speed slider's minimum from 50?

This website is a bit of a godsend for someone who's still learning the fundamentals of sight reading. However, two problems stand out that would greatly improve QOL and would, I imagine, be quick fixes:

1. The scroll speed slider can only go down to 50. I'm practicing sight reading chords for the first time, and that is still quite fast, especially if I'm trying to be conscious about good form. I think a tempo of around half that could still be useful for beginners who want to practice a relaxed pace.

2. The scroll speed doesn't actually correspond to BPM but by some weird multiple, as far as I can tell.

Just bumping this as this would be amazing for me too!
