Creating a subsequent version of an existing proof by dragging a new file on top of the first is very convenient, as it retains the settings of the previous proof. BUT preserving name of the initial proof (e.g. "filename_v1") without an option to retain the filename of the subsequent proof (e.g. "filename_v2") is a huge shortcoming!
For example, if the first version is called "proof", and I drag a file called "proof_v2" on top, the Documents area still shows this as "proof", AND I don't see any indication anywhere that the 2nd file uploaded was really called "proof_v2". Even when trying to download, it doesn't pick up the 2nd filename, but just offers to save as the first filename.
There needs to be an option to retain the actual filename. Without this, this messes up our workflow as we rename subsequent versions.
