Just found some time again to update the installer project for Package Explorer. Last year I've written some extra code for the following features (new in version 2.1), but never got round to creating a new release.

- Save package parts to disk, right click in the document inspector and choose 'save as...'
- Display directory structure in the document inspector. Toggle-able along with display of relationships.
- Open a document as a command-line parameter
- image editor is reactivated

and most importantly: the installer project now creates file associations between Package Explorer and docx / pptx/ xlsx files. In the windows explorer right click context menu, the Open With item now shows Package Explorer. One downside, now I need an application icon to make it look cool.

Hope it helps
