Crosshair customization and ability to render future crosshair

[mationai]

The ability for crosshair to show x-label on future bars would be nice. Eg. if on Daily chart, and crosshair is 13 bars in the future, it is useful to show the date, weekends adjusted.

The ability to customize its labels would be nice. Eg:

y-label: "$3.55 (n%)"
where n% is +- % from last price

x-label: "2021-11-11 (5.2 mo. ago)"
where "mo" can be "days", "weeks", "years" on daily bars, and shorter time frames in intraday.
