TOPIC: Expanding caption field

I would like to have the caption field under the photographs expand as more gets type in it.  I use it not only for a few words caption but also for longer explanation.  It is awkward to proof read and edit a long comment in a short box. 

Yeah a few guys have brought this up. I'm working on two possible solutions. The first is an option where you could add the narrative to the section and select it from the drop down box like you can now, but the comment will be removed from the area above. The second is to just allow the box to expand. Not quite sure which direction we'll go in. Any comments would be appreciated.

I vote for expanded box

How much do you guys put in the box. Does anyone go beyond what would fill two lines of text in the physical report? Seems like if you add too much the look of the report will be stretched out. Just trying to figure out how much to expand it.

I have some pictures that have 5 lines of text under it.  It doesn't make the report look stretched out.  It just looks like text with illustrative pictures. 

Even having it expand to 2 lines of text on the report would be an enough of an improvement to me.  At least then a sentence could be read without continual scrolling, this would make proofreading much easier.
