Snapshotting / Timestamping of data attributes
I'm finding that we often end up rerunning analyses that update sample/pair/pairset attributes. We also do local updates to input files and push those to workspace attributes. However, these don't get timestamped, making it impossible to tell which workflow (or workflow snapshot) actually generated these files. It can quickly become hard to know which version of a workflow or upload generated a file (without picking through the Monitor tab).
A creation timestamp for data / workspace attributes, visible on the table browser, would go a long way to sorting this out.
