Allow me to read a box document or folder in read-only mode. If I accidentally touch or slip with the mouse - I modify the folder/document. "UNDO" will only do a little bit - but in this case I KNOW I am only browsing a folder that I will be contributing to. It's a bit of a downer to see a document marked as modified today (last modification was a year ago by the document creator) because I missed the CTRL button and typed a "c" into the text. UNDO (CTRL-Z) fixed the doc - but now it looks like I'm the modifier. This just seems all wrong.
