I prefer dark mode in general, but it’s difficult to use in Figma, mainly because it’s so hard to distinguish the groupings in the Design panel from one another. (E.g., Frame, Auto layout. Layer, etc.)
The delimiting lines between the groupings are so dim they might as well not exist, so the whole panel looks like one huge blob of controls. “Center” (a stroke setting) looks almost as much like a control header as “Layer”
I imagine this will sort itself out when Figma improves its ADA compliance. And I understand the aesthetic appeal of sparsity, but in this case it’s harming the user experience.
