Any possibilities to have Blender as a file viewer?
I sometime have to handel several filetype that contain diefferent Models. It would be nice to register Blender as standard for that filetypes and have a fast and easy way to see their content.

Open another Panel and set the type to File Browser… It’s built-in!

The Idea is not to show People anything other than the model if they double click on a supported filetype. I would like to use Blender as file-viewer for People that never before use Blender as modeling software.
The possibility to use this Viewer for more than showing files would be a feature but not the main usecase.
