Description

When using the plotter, you can select the magnifying tool and zoom like in most other applications using the left mouse button.

But I'd expect to go back to the previous zoom level by right clicking the mouse. Instead we have the option to rmb-drag to zoom out again which seems very counter intuitive.

Contributor guide

Research direction
Look for the zoom handler in the plotter code (likely in a file related to the magnifying tool or plot interactions). Trace the mouse event handling to understand how right click is currently used and how to implement the expected behavior of resetting zoom level on right click.
