Users edit/delete their own files and more functionality

Hello!

I have several questions about this plugin and would appreciate any help. We are also OK with editing the inside code of the plugin to get these functionalities, but it is not easy to understand other person’s code.

Here are the questions:

1) Users can upload their files in front-end , using Upload button. But is there a functionality in this plugin that allows users to edit/delete their own files in front-end?

2) Can we add some additional file properties, columns to be displayed? For example, we need to indicate whether publication (file) is for the domestic or international conference.

3) While uploading file we can choose contributors. Question is: can we display all contributors to the file in a table in front-end? Specifically, a collumn with the names/usernames of all contributors.

Please, help us with these questions, even if these functionalities are not available at the moment. As I said we can look into the core of plugin to make this work, but without help of plugin developers it would be extremely hard.

Also if we succeed we could make these fuctionalities public, so that everyone can use them.

Thank you!
