The display and drawing colors on the time-based chart are not reflected across multiple charts.

For example, even if you set the timeframe display for a horizontal line drawn on a 4-hour chart to "Current timeframe and below," it will remain visible on the daily chart.

Similarly, if you change the color of a horizontal line drawn on the 4-hour chart from blue to red, it will remain blue on the daily chart.

Moving that horizontal line even slightly will apply the setting to all charts, but having to move it slightly to apply the setting is cumbersome.
I would like settings changes to be reflected immediately across all charts.
