Suggest amplitude control changes #71

Test device Dell Operating System Win 11 Browser Chrome Problem description For https://github.com/phetsims/qa/issues/724. These are less bugs, and more changes that may be good to consider. On the 1D screen, the y axis has a much smaller range of amplitude you can drag the points than the x-axis. On the 2D screen, while you can have partial amplitudes by dragging the points, you can only get min or max levels when using the amplitude sensors on the right. In the 1D screen you could control these amplitudes with a slider.

In https://github.com/phetsims/normal-modes/issues/67, @ariel-phet requested the reduced ranges for the ampitude sliders in the 'One Dimension' screen. So I'll let him respond to this issue.

@KatieWoe -- in a published version we will want to restrict the x -axis dragging on the 1-d screen, but this would be a complicated change for the prototype so we punted for the moment.

On the 2-d screen we should tweak several things (including your suggestion of amplitude readouts/maxes) but again, this was deemed too much effort for the prototype.
