Add Drawing Tools Support to Heatmap View

Hello,

Currently, it is not possible to draw objects directly on the heatmap view (such as lines, zones, or annotations).

This limitation makes it harder to mark important liquidity levels, reactions, or areas of interest directly on the heatmap during analysis.

Request:
Please add support for drawing tools directly within the heatmap view, consistent with the standard chart experience.

Also, could you let me know if this feature is planned and whether there is an estimated timeline for implementation?

This would significantly improve workflow and usability for order flow analysis.

Thank you.
