Zoom - zoom lock - change state from persistent to session

[user0]

XnViewMP 1.11.2
Windows11 (25H2), display resolution 3840x2160, win scaling 150%

Viewer / Browser-preview
app keeps the 'Lock zoom' state enabled after restart, which is inconvenient because:
- only options from the Settings menu should be persistent (also state from one Viewer tab should not carry over to newly opened one)
- 'Lock zoom' is temporary by nature and does not seem suitable as a persistent setting
- for persistent behavior, 'No fit' auto-zoom could be used instead (though ideally it should zoom to 100% only, but that is a separate issue)


Suggestion

• change 'Lock zoom' state from persistent to session only
  reset it to disabled when reopening a tab if the session was not saved

It's not only Settings menu items that persist..

Other things are also remembered in the viewer, even across restarts, even though they do not have a direct entry in Settings. Examples:
-Info Overlay visibility (in tabbed viewer, not fullscreen)
-Histogram visibility
-Shadow/Highlight clipping

Lots of things persist in this way. I don't think they all need individual items in the Settings dialog.

Whether lock zoom should be persistent is really a matter of individual taste. It does not seem to me that it cries out to be treated differently than things like I listed above...

there is no room for 'individual taste' here

'Zoom lock' is standard functionality in image viewers that temporarily overrides other zoom modes.
And, as I already mentioned, there is other, more logical way to achieve the same zoom behavior.

It's not only Settings menu items that persist..

Comparing a complex zoom mechanic to simple toggles makes no sense.
Also, the fact that a few simpler features do not follow consistent session/persistence logic is outside the scope of this post.
