Probably one of the quickest and simplest plugins to write that has proved pretty useful to a few. Mofux is in charge of the code now so if you want any changes ask him... sorry buddy but its all yours now .
You guys may want to be more specific...i've been using the refresh plugin with MP .2.2.0 (not SVN) without any major problems. Trying to use it with an OSD and some overlays showing will cause it to black screen and force a restart of MP. But the solution is simple; back out of the OSD before refreshing.
Any errors i've received in the logs after refreshing are due to other plugins, almost exclusively plugins that threw errors on initial mp startup.
