Branch filtering obliterates branch graph

We have a very active repository with many development branches. On top of that, we do build-branching ("build") and version-tagging ("version") as part of our build process, which results in the revision graph becoming very noisy. The actual source revisions easily get lost in the noise.    I've discovered that a branch-regex using negative look-ahead "(?!build|version).*" is quite effective at hiding the revision information from the build branches and version tags. But to my dismay, it also kills the view of the graph. This makes the exercise entirely pointless. If I wanted a log view, I'd be using the log viewer, not the revision grapher.    Am I missing something here?    SmartSVN Pro 7.5.4 on Ubuntu 10.04
