Attachments: Customer Database

We have now the ability to attach Invoices to the Supplier .  It would be great to have the facility to upload documents to a customer eg a pricing contract, emails regarding any changes to service.  Sometimes, changes are made and when you try to go back to find out why, it is a chore to locate the particular paperwork.

I can attach in Memo at the moment, but my Admin cannot see anything that I attach, and vice versa.   Even if we had to facility to see each others attachments that would be great.
