The thumbnail view is, of course, really helpful but I have one problem with it for files from which I have several versions (i.e. several stages of editing).
When using the thumbnail view I often would still need to know the file format to be able to distinguish versions. For me it would be great if the thumbnails could be overlayed with file format icons or text for (doc, pdf, tif, jpg, psd, psp, ....) - as an option.
