Zoom slider (on panorama view) is not practical
On the panorama view, in the "Controls" panel, there is a slider to change the zoom level.
It is really not practical:
- with firefox, the slider is not even displayed (probably black on a black background). With chromium however, it works fine.
- even more fundamentally, a slider is not practical to use. It would be more user-friendly to have a "-" button on the left and a "+" button on the right, or something similar.
