One of the key features I miss in gedit-latex-plugin is proper indentation for wrapped lines.
With proper I mean that when a long line is wrapped over several screen lines, it should be (at least optional) to have them all indented.
This would greatly improves code readability. This is done, for example, in Kile. I attached a screenshot of both.
Footnote: there is an option "automatic indentation" in the gedit config, so perhaps this is already present, but it does not seem to do anything. Sorry if this should have been a bug report rather than a feature request, feel free to move if this is the case.
