At this point, bAssetHound is able to:
save into files the texts & packed images
thumbnail the mesh objects from multiple angles
show the color of materials
show group members
show whether image paths are valid
sort meshes by number of verts/edges/faces & a few other things
At the github link, if you wish to have a zip suited for install via blender’s user prefs, choose the zip from among the files – if you download the whole github project as zip, you will have to manually relocate the bAssetHound folder into your addons folder.
Also, since this is still very beta, the _dbg = True line – it is left on and leads to an operator in very impolite location ( top left ) which shortcuts to using scan of blend files on desktop for a few predetermined categories.
to be continued…
not tested yet, but sounds very nice. 
Here is a small error report running it on a folder full of blends.

Ok I’ll have to check into that. The override is still a bit shaky, and the only way I made it work took a session with pdb.set_trace() just before the view_selected op. I wish I knew what context members it was looking for… Thanks for the heads up and sorry It doesn’t work for you yet. I updated the github today with a little bit more work but I doubt it pertains to your problem.
