XYplorer Beta Club

Is something out there that defines what all the tweaks do and is kept up to date?

No and there likely never will be.

there's a list of tweaks that are supported by the tweak() function here: http://www.xyplorer.com/xyfc/viewtopic. ... 52#p120052

And there is the change log: http://www.xyplorer.com/support.php#resources

Thank you all for the info.
