For Windows the Explorer PlugIn is available. It allows to view the contents of the file repository and to download and upload files. An upload creates a new version and asks for a description of the changes . In Windows as well the synchronization is available like for Mac. Unfortunately sync rarely (only if multiple authors work on a file) creates new versions and does not allow to indicate the changes. Please add the capabilities to create new versions and to access files without the need to synchronize these to a Mac.
IBM Notes already has this kind of plugin available based on Eclipse. But not all Connections users run Notes and the Notes PlugIn does not run as good as the current Windows PlugIns.
