XnView Software

Under Settings / Interface / Mouse:
please consider adding these 2 options so that they could be assigned to any mouse button (or mouse button + modifier Ctrl/Alt/Shift):
- Reset Zoom to 100%
- Reset Zoom to Fit Screen

Sometimes you want to check the focus on a photo or a small detail,
but you need a quick way to reset the Zoom back to Fit the Screen (or back to 100%)
Currently there's no way to do it (with the mouse) unless I'm missing something.

Cheers.

there is "Zoom & move" (Shift+LMB) command - it always zoom-in to 100%,
works only for zoomed-out image which zoom scale ≤ app window size

I would probably think in a direction of adding options to this command, eg

• add "custom zoom scale" combobox
  so it can zoom to whatever you need, eg 50%, 150%, etc.

• add "work from any zoom level" checkbox
  so image can be zoomed from any to any zoom level

close example - click-to-zoom in Lightroom, which jumps between 2 custom values
