Explain navigation mode
Choosing the navigation mode (trackpad or mouse) is not evident and the navigation is not natural when you are on trackpad mode but using a mouse. Ther should be an interface explaining it is possible to change it

Pointer should be the default mouse, with panning being a tool. Additionally, panning should be optionally possible via middle mouse button + dragging or ctrl+click and dragging.

For the longest time, I thought the mouse navigation mode was broken because I couldn't pan around the image. Finally, someone else figured out that the pointer tool had to be deselected. It was not at all obvious to me.
