In the New V15 I am finding that if I make a New Cations (aka Text) file form my project the current text file does not appear as a new item in my project. What if I want several versions just like I may take a Raw clip of video and edit it several ways - each new sequence gets a new working slot in the project. The new Captions (Text files) are not automatically created. I have to export the .srt and reimport it if I want various working files.
Because you can not image why I need this does not make my need any less valid. Old captions created their own "holder" that I could duplicate and edit independently.
