Save attachments under ~/Downloads
Attached files should be placed not in the app sandbox itself but in the ~/Downloads folder.
People might delete this folder accidentally — what happens to the downloads in the messages?
Does deleting a message delete the download also?
It will require additional folders in Pulse
If downloads are in a nested folder structure, e.g.,
From |_ aral |_ 000000001-2015-08-06T06_00_53.512Z |_ SomeApp.app
Do they really provide any additional findability? (The expectation is that downloads are placed directly in the ~/Downloads folder.)
Triage: this is low priority and not as straightforward as it might seem.
