We have milestones set and work with these. There will be no open documents for now, sorry. We just don't want to "ruin the fun" with endless discussions about something that isn't even in the game yet.
/Edit: One thing I forgot... Right now, we are pretty busy with fixing bugs, etc. That's why we didn't released any bigger update since some time. The additional content, that we have taken over from suggestion-board, was everything more or less easy to add and could be done beside our regular stuff.
