I'd like to know which TeX editors have syntax coloring options which color/highlight the math mode text between the $...$. This way it is easy to see when you are missing a $.
Currently, I am using TeXShop, but despite some discussion in Nov 2002 on MacOSTex, this feature seems to have never been added.
Hence, I'd like a list of editors with this feature. (I am interested in Mac OS, but it may be useful to have a more general list.) This is a difficult thing to search for on Google without just trying each editor and looking at it's syntax coloring.
UPDATE: Per doncherry's comments below, please add this information to the big list of LaTeX Editors/IDEs.
