TeXstudio

TeXstudio is a fully integrated writing environment for authoring LaTeX texts. As a result, TeXstudio has a variety of capabilities such as syntax highlighting, an integrated viewer, reference checking, and other assistants. TeXstudio is open source and compatible with all major operating systems. TeXstudio was split from Texmaker in 2009 due to the latter's non-open development methodology and differing attitudes on configuration and functionality.
