After searching the issue queue and lots of trial and error, our users are still unable to edit the filename in the file upload process. In issue 2223381, it appears that @merlinofchaos added this functionality. However, the option to change the file name does not appear in the upload process for our particular install.

We have file entity paths installed. Could there be a conflict between file_entity and fe_paths? Changing/removing the default file name tokens in fe_paths module had no effect. In file entity settings, "Skip scheme selection" is enabled but the file type selection and skip file fields options are not.

Drupal - 7.38
Panopoly Distribution - 7.x-1.24
File Entity - 7.x-2.0-beta1
File Entity Paths - 7.x-2.0-alpha3+2-dev
Media - 7.x-2.0-alpha4

We would appreciate any suggestions that others may have.
