There has been a lot of talk about improving captions and I feel that separate captions for main media types is the way to go i.e. Audio, Video and Images.
Doing this would make my caption expressions significantly easier to create, maintain and change.
Also for images I have a lot of info in my expression. Editing it can be quite a pain because I want separate info to appear on different lines. I am doing this now by including the carriage return (The enter key if that's correct (See Image)) in my expression. This can be quite messy and difficult to change.
What I suggest is that for caption input each section has three expression input boxes. One for each line. This would make it much easier to manage. MC should honor the old way as well for people who don't want to change their expressions yet.
