First let me give props for a great plugin. It's elegant and functional.
There seems to be an issue with captions however. I'm trying to insert images and I want them captioned. I'm also an trying to set the title the same as the caption so it shows up as a caption when opened in a Lightbox overlay (not sure why LB can't read the regular caption info).
Problem is that whether caption or title, the settings in the default media uploader do not seem to cross over to File Gallery. For example. Captions I have previously assigned to a file in the default uploader do show now up with File Gallery and visa versa.
This means that to get what I need I have to manually insert the caption on the image in File Gallery, but then I have to open the same image in using the default method and add the title. This wastes a lot of time and causes confusion.
I'm not sure if this is a bug or by design, but it would sure be nice if a caption added in one place would show up in the other.
Keep up the great work... Gav
