I just sent the following to DxO support:
I do not wear prescription glasses - don’t need them, yet as Photolab develops, the UI text size gets smaller, and I’m having difficulty reading some of the menus, especially those inactive palettes when the text is a slighlty lighter shade of grey than the background - a severe lack of contrast. It negatively effects both usability and accessibility, and I see no options to change it. My other apps don’t have this issue.
While I recognize you’re attempting to pack a lot of info. into a smaller area, consider other options, e.g., use a shade of yellow on the text of active/selected palette areas while applying a brighter shade of white to inactive areas rather than the current grey text on grey background that’s almost unreadable. Contrast it as important as text size when making palettes/menus this small, and your current design has taken both too far in the wrong direction.
