Hello Laza,
I changed smartphone since my last post above and even with a FullHD+ screen, the problem is still present (tested on a Pixel 6a).
As you can see in the 2 new attached screenshots, the side margins you have changed in version 2.3.0 does not seem to be set in pixels, but somehow related to the screen size.
This side margin is way too large and makes the reading of the comment quite awkward. This was quite OK before: why did you change that?
I suggest you the following:
1) Set by default the size of comment box (i.e. the box with dark background in my case, including image numbers and comment) to the maximum width of a picture, given the screen orientation. See red annotation in screen shot #4.
2) Optionally, define a new user-defined parameter that can only increase the margin (and thus reduce the width of the comment box).
I regenerated all my albums with the version 2.3.0 to fix other issues, but I saw this regression only later: so now I have to redo it once again, once you will have fixed this
.
Thank you for your support.
