Users need method to open downloaded file/folder
When one downloads a file in the desktop app, such as an image from a thread, a pop-up notification says that the file was downloaded, but gives no inkling of where it was downloaded to. Some of our less technical users will find this extremely befuddling. "Where did the file go? Maybe I need to click Download again. And again, and again... Now I'll call IT."
Clicking the download notification should pop open Windows Explorer to the location that the file was saved in (i.e. Downloads), or open the new file itself.
