Could the labels in the UI be full white rather than light grey please?
The light grey on dark grey are very difficult to reader for those of us that are older with tired eyes.
Agreed, and proper system dark-mode support would be great; the contrast between the dark UI and bright dialogue windows can be very jarring!
The label are gray to distinguish them from the editable value in white. The contrast could be changed a bit, but we do not want to change the design overall (we did not hear complaints about it).
However, did you try to change the scale and the color-profile of your display in macOS System Preferences / Displays ? This may improve lot readibility, as macOS tends to make UI very small and uncontrasted.
