As of Sept 30th , we've re-enabled user comments at our SVN repository PCSX2 @ Googlecode.
Comments have been re-enabled primarily so that we can get user feedback again on plugins and the current legacy gui updates. The trunk of svn (the new wx gui) is still too volatile for user comments to be of much use, so don't be surprised if we pretty well blow off "bug reports" relating to it.
(and yes, top priorities for implementation in the new gui are framelimiter, savestates, and the advanced cpu options -- along with bug fixes and memory leak fixes. No timeframe estimates: They'll all get done when they get done!)
