[feature request] add references field
My Paperwork version: 2.0.3 as from Arch Linux community repository
In the document's properties I'd like to have option to reference other documents. This is helpful e.g. to reference an invoice and a contract when filing a payment reminder or when there is a longer communication about one subject (e.g. conflicts with insurances). When such a feature is implemented my expectation as a user would be the reference will automatically be added on the referenced document as well. It may also be of interest to add an unobtrusive marker on documents that have references for easy filtering. as reference ID I suggest the date/time as it is already used as ID, as the user manual mentions.
