I live in the latex bundle, but this feature request may be relevant to others.  I would like to be able to move blocks of text in the latex file by simply moving corresponding headers in the "Go to Symbol" sidebar.   This would replace my need to use OminOutliner to organize material.   (There seems to be no satisfactory way to port a Latex file from TextMate into OmniOutliner without a great deal of hand work.)

That's an interesting idea. Don't about about in general, but we might be able to have something like this in place with a custom command using a custom nib with a tree structure, where it presents the various sectioning items and you can then move them around. Once you are done, the command then rearranges the text and replaces the entire contents of the current document with the new contents. I would be very hesitant about making it work across multiple files, but within a single file it shouldn't be too hard to do. Such a command would of course have to work under the assumption that, once it encounters a \section{} command, then everything until the next \section{} command is part of this section.

A related feature request would be a Latex logic checker.  No matter how we move blocks around, we may wish to check that the references maintain their logical ordering.  It would be nice to have a command to do this for us, especially for long documents.  I am no programmer, but I imagine this should be easy to do -- find each \ref that occurs before its \label.

But very often you want \refs to appear before their \labels. I don't see how you can establish a logical ordering by determining that a \ref appears before its \label. Plus, you might also have multiple \refs.

Or perhaps I have misunderstood what you mean?
