That's a neat utility!
Feature suggestion: hold B when pressing left/right to step only a single value.
In playing around with it a bit I find trying to fine tune a value often results in jumping the value by a large amount.
For example: Clock set at 1, press left, clock is now at 16.
This can be nice to quickly cycle through values, but it's would be cool to be able to toggle single value stepping vs multi value stepping.
