Yesterday was the first time I'd opened iMovies in Mavericks. But surprised at the new layout but it cleaner and I do like some of the changes. Only problem is when using titles I can't seem to change the font or size, with the text selected the options for change the attributes are greyed out. I did try several different animations but to no avail. Seems a bit strange not having the ability to at least change the size of titles, or is this a bug?
