and noticed, that Mike wished that it would be possible to annotate designs in Figma, to consider accessibility during that phase („Shifting Left”). Now since Figma is acquired by Adobe I don’t have high hopes that this will become a thing. However, since Penpot is Open Source I could imagine that it could be a useful feature to implement.
I agree that better annotations would be helpful, for accessability (like alt-text, announcements, tab-order), but also for showing margins/paddings, annotating behaviors etc.
At Wikimedia, using figma, I did this with having elements in an asset color (typically magenta) that I could toggle from and to being transparent. This was ok, but cumbersome.
One way could be to be able to “tag” elements as annotation or having a set of annotation shapes/objects. (Annotation layers are a pain imho; as would be reflecting HTML accessability directly (as component properties or so?) – that probably combines the bad parts of both coding and WYSIWYG)
