I'm so glad I'm not alone here. I've made countless videos with iMovie over the last year or so, and now that I've "upgraded" to iMovie 10 I find myself struggling with even simple tasks. Why on earth can't I change the size of a text in a title any more?? I'm finding that a title with more words is automatically made much smaller with no option to change it, so my video looks awful. Apple, this update feels like a huge step backwards.
Incidentally, is there no simple "captions/subtitle" option available in iMovie? It seems odd that there are so many ways to add different kind of titles, but no way to insert a series of simple subtitles at the bottom for those with hearing impediments. Am I just looking in the wrong place here??
