There is now support for AccessKit (https://github.com/AccessKit/accesskit) which brings accessibility to egui (a first for an immediate mode GUI?).
There is also better table support, nicer keyboard shortcut handling, better looking text in light mode (still not great, but better).
See more in the changelog: https://github.com/emilk/egui/blob/master/CHANGELOG.md
