Though this is a huge step in the right direction to fix a really dumb bug in FCP that should have been addressed loooooong ago, this is only going to be useful if you know the EXACT NAME of the font because you have to type it in (and it's case sensitive)...and it only sees the font family primary name...not the 20 variations inside a suitcase (I have 4000 + fonts outside the system fonts folder controlled by Suitcase Fusion). There is no font drop down / browsing capability.
P.I.T.A. - but a step in the right direction.
When life gives you dilemmas...make dilemmanade.
