Open Office format support is in the roadmap, the first integration will be through spreadsheets.
An RSS reader is also planned, but work has not been started.
Imap support is on its way, but definitely not for version 0.9.
Sorry, but no dates yet.
If you wish to translate, send the translated files (stored in /languages) to contact@opengoo.org . Or, if you wish, email us for more instructions.
Thanks,
