The latest version of the downloader has an installer package (.pkg) which you should run and it will install the necessary files in the right place for you. However, you must have the latest OmniOutliner Pro 3.6 beta installed (beta 2).

To add the Kinkless buttons to the toolbar if they aren't already present, you need to have a document window (sensibly, this will be your GTD one) open and select View>Add/Remove Document Specific Toolbar to add the kinkless buttons specifically to that one document (you probably don't want to add them to all document toolbars as they won't be of any use).

Does that help?
