I use WordPress 321, Atahualpa 371, and qTranslate 2.5.24. I like the grouping scheme of SM very much. But unfortunately it spoils the ability to display post titles in different languages.
qTranslate stores all language versions of a post in one wp_post field, separating them by different tags:
[:en]Systemic Questions [:de]Systemische Fragen
where [:en] denotes English, and [:de] German. According to the language selected WP shows the appropriate title.
But SM shows all languages in one line, e.g.:
* Systemic QuestionsSystemische Fragen
Scribu, please have a look at Qian Qins tutorial how to make plugins working with qTranslate:
