ZigZag pro indicator improvements

Hello, I would like to suggest some needed improvements to the ZigZag pro indicator:

1. The amount of digits after the decimal point should match the chart settings.
   Currently it displays 3 digits, cluttering the chart more (see screenshot below).

2. Add a "Show Delta/Volume" option that displays as % behind the delta.

   

3. Add the same Visualization settings as the Candle Statistics indicator.

   

4. Add a Horizontal Offset setting for the text displayed at the current candle only, allowing for better visibility.
