This is great. Thanks for taking time and wok on this, is a much-needed feature. The mockup you shared is a great improvement already from the screenshot in the GH repo. In this case, I feel I'm missing the original dropdown.
Anyway, just wanted to pin this out as it was passing through my mind. Ping me when you put your hands back on this PR, I'll be happy to explore more UX/Ui options.
