Is it possible in DEVONthink 3 Pro to turn off the document type stamps (RTF, RTFD, etc) that appear on every thumbnail? (See screenshot)
Yes, I know how to paste an image over the default thumbnail in the document Info panel, but I’m talking about the 1,000s of RTF documents I have that I’m not going to manually paste custom images into. I readily admit that this is not a big deal… there are far worse problems in the world… but seeing RTF on every thumbnail just looks clunky to me and reminds me of working in DOS. 
Basically, it just seems unnecessary to show the document type on thumbnails. DEVONthink already provides very simple ways to see that or to filter a list of documents.
As I said, not a big deal… just a minor pet peeve I was hoping to eliminate.
