Poor grammar: "less categories" should be “fewer categories"

In the “POPULAR CATEGORIES” display, there is a link at the bottom that alternately says “More Categories” or “Less Categories”. Is there a way I can change this string (“Less Categories”) to a grammatically-correct “Fewer Categories” without having it overwritten by the next plug-in update, or should I wait for it to be fixed?

Ideally, I’d like to override the Word Capitalization, too, in favour of Sentence capitalization. Same request, really.

Clients don’t understand when grammatical errors like this are not trivial to fix.

Thanks!
