Favicon

Can you please add the ability to upload a favicon? For those of us with multiple client workspaces open at once, it is hard to tell which tab is the one for which space unless I click it. (I currently have 6 open in my browser, and they are all the purple H.)

This has come up in our organization as well - having a customizable favicon would boost our brand and help our users recognize the difference between different workspaces more easily. 

Any chance we can bump this up for consideration?

Having the ability to add a favicon from the admin dashboard would be amazing.
