About panning: indeed it seems to work well.
About zooming: please confirm that now, zooming can be done only via
mousewheel. If so:
- you should update "How to use"
- how do I proceed to zoom a particular area? selecting the area gave
me a better control over which area I want to zoom
You need to zoom in to a certain level of detail. You can then use panning to move around and explore the plot. That way you can zoom into a particular area.
I agree that the earlier inbuilt zoom where we could select an area to zoom was better. Its effectively a zoom and pan functionality combined in one. In my opinion, if we use the inbuilt zoom then including a separate panning feature is not that necessary.
