How to browse uploaded assets on the front end? I have a frontend entry form which included a file field to upload files to the entry. All works fine. I even have a delete function to remove individual uploaded files from the entry. 

The problem is if a user wants to attach a file they have already uploaded. Uploading the file results in the same file uploaded but with a different filename (a timestamp added to the end).

This is going to result in unused files being left on the server and a nightmare version control going on - people left wondering what version is correct, which is being used, is it safe to delete the old ones etc. 

So ideally what is needed is the user can browse the assets uploaded on the front end and ideally be able to upload within that. 

Is there a facility to do this? 

Thanks
For Craft 3, there is UploadIt, a  front end asset uploader.
