It's easier for me to review posts that are tagged with one of my favorite tags, because I am more likely able to decide the correct action for the review task.
Therefore I think that reviewing could become more efficient if there was an option that installs a filter based on the users favorite tags. Of course this filter could be limited to e.g. 3, maybe randomly chosen, tags for performance reasons.
Furthermore, the filter should get auto ignored if it doesn't return any results, so that the user can go on with reviewing without interrupting his workflow.
tag=tagname
to the URL (see here). "Filter by my favorite tags" is also already part of this MSO request. There's also one for wildcard filters.
