UI issue

Bruno Simon added your tweakpane to his portfolio, and because of the msasave usage, the UI hits the limit of my 27-inch screen, but I can't scroll through the options, so I did a simple fast solution with CSS:


```
.tp-rotv_c {
    overflow-y: scroll;
    max-height: 90vh;
  // or basically, how did you call it before building!
}
```

SO, if you make it in the package itself, it would be better!
