RText is a really great achievement. I has been following the RText development since 2009, and I like it a lot (before I was working mainly with JEdit).
I'm thinking about how to replace aging SCaVis IDE (from http://jwork.org/scavis) with something based on RText. I have however a small question: does "ctags" method work for LaTeX files? I noted that the left panel with ctag is empty for my LaTeX document (but it works for Java files).
SCaVIs IDE uses a simple Java-based ctags, but it's is done only for a few languages.
