Regarding the 12.17.3 beta, is it possible to add a configuration page for controlling the mouse wheel?
A preferences page for the scroll wheel listing the varous key combinations and what action they should be mapped to would be excellent.
I would personally move horizontal scroll to be on "SHIFT" so it matches other software I use, and disable GAMMA which is a constant source of annoyance (obviously because I keep accidentally using shift for horizontal scrolling)
If I can ask for one more thing - This might be a macro rather than a preferences option,
When viewing an image in full screen, I would like 'ESC' to exit full screen mode.
Once in window mode, a ESC would then exit the viewer as it already does.
