Sounds like a good addition.

While that's a fine addition to the current situation. I'm
specifically trying to expose the keys you use to change isearch
options. I suppose we could display those in a help-echo hint on those
mode-line abbreviations, but I prefer to make it very clear to the
user that they can type a key to see options.

You see that `Isearch: ' prompt every time you hit C-s, and that's
right beside the text you're typing. This Help reminder would be off
to the right edge (so it's far from the text you're typing). Besides,
if you just type C-h once, you'll see a buffer explaining (among other
things) how to disable this reminder.
