Q: Why doesn't the grid on the chart change when I change the scale, and can I change its density?

The horizontal grid is fixed: it is always 10 bands across the chart height, and when the scale changes only the prices in the captions change (at 20% scale the band step is 2%). The density of the grid cannot be set. The grid colour and opacity change in Settings → Theme and colors, the “Grid color” row.
