Hi Dick,
It sounds like you're after something almost like a 'Table of Contents' type widget? There is a pageLevelProgress extension but as the name suggests, this is limited to displaying the the progress through a specific page.
The Resources drawer wasn't really intended to be used to link within a course, it was supposed to be for external resources, e.g. PDFs, links to other websites, etc. In saying that, it would be a good idea to have an enhancement to Resources which at least can control whether the resource displays in the same window or a new one. Feel free to add this as an enhancement issue here:
