UX Notes

Manual Input

To edit the value manually you need to double click the input which will automatically put the input in focus, select the text content, and allow typing.

Step Precision

The step prop represents what value the result of a drag operation will be quantized or "snapped" to, otherwise if we strictly only allowed moving by step, then for example a range of 100_000 and a step of 1 would take about 53 average computer screen's worth of dragging to get from min to max - not a great user experience! Fortunately for precision - besides typing into the input manually - you can hold shift while dragging to make fine adjustments that exactly step increments.
