the first problem is with the document tags. They do not appear to be compatible with the standard wordpress tags. I do not consider three different tag clouds - wordpress tag cloud, buddypress group tag cloud and doc tag cloud to be conducive to streamlined easy hyperlinked surfing.
the second problem is screen formatting. When I click the docs option on the buddypress group menu the group admin icon gets shoved over into the right side panel... not nice..
the problem is that the plugin announces on the dashboard that it needs to do an upgrade and provides a button to do so. After clicking on the button, the plugin goes off doing something then comes back stating upgrade completed and immediately shows the "upgrade necessary" banner again.
This is on a clean wordpress install using the themekraft community theme.
