This is really great, I love how easy it is now to install and update plugins! Really a great piece of work!
However, the updating functions in "My Plugins" doesn't seem to work. I saw today that there was a new version of Fredo6's Bezier Spline and still the Window was empty, when I activated "check for updates". I have to wait until other plugins get updated in order to find out whether this also applies to them. I'm running Sketchup 2013 Free version on Windows 7 64bit and I just noticed that apparently I don't have Internet Explorer installed (must have uninstalled it some time but forgot about it). But the plugin still works, except for the update function.
