updating name on replacing document

Dragging a file over an existing document will replace the file contents, not change the name.  In the case of your example the document really should not have the version number in the title, so the new version of "document.pdf" would overwrite the older version of "document.pdf".

I completely agree with you; ideally, the file name shouldn't be altered. Unfortunately, the files we're dealing with come from external parties, and we don't have any control over their naming conventions. To address this, I've created an additional field where I store the original name of the file. The idea is instead of altering the current document name, this field should be updated when the file is replaced.

I don't know whether there's an easy way to do this.  I don't recall - but maybe someone else does - of a configuration setting, at least.
