Allow Optical Margin Alignment to apply only to punctuation.
Optical Margin Alignment does a great job allowing quotation marks and hyphens to hang into the column gutters, but it also make characters like A, W, and T do the same, which is often too high a price to pay. Fix this by allowing an option it to only apply it to punctuation.

I would love this feature.
I work for a large company and our brand uses fully justified text on all of our artwork. I can't bring myself to turn Optical Margin Alignment on because alphabetical characters become too ragged on the left hand side of the column. So we put up with punctuation looking bad on the right hand side of the column. Changing the point size in the Story palette doesn't seem to help. It's impossible to get a nice looking paragraph of fully justified text if a full stop or comma happens to fall at the end of a line.
