Hello
Noticed "Auto list all available translations from program/localization/" in your roadmap and wrote something up. You can download it from http://van.gla/rc/rc_dynamic_lang.tar.bz2
I rewrote rcube_list_languages function in program/include/main.inc and made extra file "info.inc" in every language folder. It includes $LangName variable from which the dynamic menu is built (maybe later also $LangEncoding, $LangAuthor etc. ?). The index.inc in program/localization now only contains $rcube_charsets array. The code may not be nice but it worked for me.
What do you think ?

PS. It also contains Estonian translation that i sent to roundcube@gmail.com but not appears to be in CVS.
