As suggested above: the plugin pack is a courtesy to users, there's no support for it. It comes without warranties, support or anything else. I will not release a new version simply because it's too much work, nor will I go through the effort to modify all those files and come up with a better description what they do. Plugin authors are welcome to add more details about their plugins in textual form to the plugin code, so more descriptive texts are turning up on the plugin manager page itself. Plugin authors are asked to come up with a readme file as well.
It's a huge effort to bundle the plugin pack that I won't go through again, taking into account the comparatively small amount of downloads and subsequent benefit the package gives to end users.
To me, it's an experiment that failed.
