LaTeX editor with live preview pane for Ubuntu/Linux

Gummi

Gummi is a lightweight LaTeX editor written in Python/GTK+ released as open-source software under a dual MIT/Beerware license, and was written by a BSc student of Artificial Intelligence at the University of Amsterdam, Alexander van der Mey.

The main feature of Gummi is that the Preview Pane will update as you are typing. In my opinion, this feature is good if you are learning LaTeX.

Give Gummi a try, and tell me your opinion.
