Zoom is not following the pointer, but the middle of the screen about fast-pathology

This has now been implemented in FAST and will appear in the next release. See commits smistad/FAST@d4c3311 and smistad/FAST@5c72bd8

Suggestion (1) is something I have also wanted for a long time. Same with smoother movements including deaccelerations, similar to what QuPath (and OpenSeadragon used for LearnPathology) is doing.

Agreed. This can easily be added here: https://github.com/smistad/FAST/blob/master/source/FAST/Visualization/View.cpp#L702
However, the speed it should move towards the pointer might need to be optimized.

Support for arrow keys is also quite easy to add, but which keys to use for zooming in and out?

Sounds good:) One can always also add "+" and "-" as zoom keys, but I think most people just use mouse scroll together with the arrow keys. The hard part for the wrist is repeated "click-and-drag" movements, much more so than scrolling.
