I think it would be a nice idea to have a limited Version of the "show users report" called "show my permissions" (or so).
The idea is, to give users that are logged in to SVN-Access-Manager the possibility to view their own access-rights and group memberships. In principle that would be the same as the "show users report", but the user cannot view or choose anybody else but only generate the report for him- oder herself.
Not sure, whether this is easier to implement via a new attribute of the global "show-reports" permission additional to "none" and "read" like "mine" (if so, the default for it should be configurable via the configfile, what from my opinion should be true for all of the global user rights and options), or just to include it into the the "my accounts" section without any configuration.
Probably it'll be a good idea to avoid code duplications with the standard reports :-).
