Bug Fix Suggestion: Improve Polyline Tool Behaviour

I've noticed a couple of issues with the polyline tool that make it difficult to use efficiently:

• After selecting the polyline tool, it doesn't seem to remain active in a predictable way while I'm trying to position and place it where I want on the chart.

• More importantly, there doesn't appear to be an intuitive way to tell the tool that I'm finished drawing. It continues to add new points and extend the line indefinitely.

• I initially expected the Escape key to end the drawing process, as this is common behaviour in many charting platforms, but this doesn't seem to work.

It would be great if there were a clear and intuitive method to finish the polyline, such as:

• Pressing Escape to end the current drawing.

• Double-clicking to place the final point and complete the polyline.

• Having an option to switch back to the cursor automatically once the drawing is completed.

Implementing behaviour similar to TradingView would make the tool feel much more natural and significantly improve the drawing workflow.
