When updating an existing file the original filename is maintained (example: "wireframe-3.pdf", updated to "wireframe-4.pdf" still shows "wireframe-3.pdf" in the file list, dashboard etc).

I assume this is a bug since if you change filetype (example: .doc to .pdf) to icon graphic changes appropriately to new doctype.

Another file issue Ive found is on OSX/Safari downloading any files via AC/0.7 will deliver the filename and only 2 of the 3 extension chars (ex: "wireframe-4.pd").
