In each of those examples, we said "no" decades after they were developed, and many had to suffer in order for us to get to the stage of saying "no".

Testing with "Banana... Banana???? Banana!!!!!" Yields interesting results each time, and none so far the way a human would read it.

Good work, I like the look and feel of it all.

It would be good for the dismiss of the "goal within reach" message to be permanent so each time I make a slight adjustment it doesn't keep popping up.

It would also be good to have a deductions option somehow, like the contributions but inverse - say I have a large starting amount but I want to make regular small deductions but still have the goal of increasing the pool through investment gains over time (eg starting capital of 1m, goal of 2m over 20 years while deducting 2k per month - is this viable)

Great suggestions, will do.

Not sure how you'd execute this, but I think a great method of control for rhythm would be like a karaoke bouncing ball that you control with a keystroke. eg:

  -I write out my lyrics
  -you break my lyrics down to [x] syllables
  -I choose this rhythm control option
  -I hit the spacebar [x] times, in my desired rhythm based on those syllables (maybe a karaoke style visual to guide this), & you calculate timings between each keystroke and then attempt to create rhythm based on that
