I used to use it, but its extremely font and glyph-sensitive wether or not it works. And if it doesn't work there is no easy fix (or ability to recognise it nonvisually)

You would have to use that if you want smooth antialiased zooming in and out of text.

BTW, the KiCad schematics are pretty text-heavy. You typically write down all the parameters and IDs of all the electrical components.
