If you ask me, the fact the system doesn't already do this is such a glaring shortcoming that I'm really taken aback that this is something that should require feedback! When the system was developed to produce PDFs, obviously a method of assigning filenames to the PDFs was also created - that this wasn't defaulted to the actual name of the document is stunning, and that "settings" interface allows us to set this is also stunning.

The present setup requires the user to rename every single downloaded file to get a usable, intuitive name. Honestly, I'm shocked. This is Microsoft Office and Server levels of bad.

I also cannot forward an invoice to my own assistant or to myself - I have to download first and then email a copy, which is how I discovered this flaw in the first place. 

This is meant to be a flagship accounting product?! I can't understand why people woulnd't ditch this for Wave, Xero, MYOB or anything else - and I'm on your side. Please tell the devs to implement this basic, basic stuff.
