* Filter a thread by the original poster so that only their posts are visible - many of our users aren't interested in seeing replies and only want the core content
* Create new entities with new attributes, files that can be categorised, searched, version controlled and edited by privileged users. Almost like a wiki that can be integrated with the forum.
* Keep post edit history so that if a user edits their post the history can be viewed unless removed by a privileged user
I expect none of this will exist already but my question is does the Xenforo development API allow for these types of modifications.
