There are maybe for 1.0.7 or 1.0.8. Currently 1.0.7 under developing with refactor events yet. It's dropped calendar support (not really friendly UI for mobile). I have still looking for new events layout. Can you give some?
It has never been a good idea to have multiple modules for the same task. Most of us will use XenAtendo and I can´t see why inventing the wheel should be done again, when most of us have it at hand. At least, there should be an option to use XenAtendo when present in an installation. Like you already did with the XFMG for group images. I´d like to urge you to have a look into this suggestion again, which I am backing up, too.
