Remove manual entering of Import Reference
What is the problem you are facing?
When uploading files to a library, one has first to enter manually a socalled 'Import Reference', which is not very user friendly and not really needed. Actually, it is defaulted to the current timedate and I don't really know why one would want to change this. Suggestion is to remove this from the front-end and generate the import reference automatically in the backend.
What are the possible drawbacks or issues with the requested changes?
There might be use cases where one wants to change manually the import reference, though I can't think of any of it right now, at least not with the official frontend. Maybe the possibility to change it manually should be kept in the api as optional...
