Option to Minimize or Draft an Email

We would like for Neos to incorporate a function that allows us to minimize or draft an email.

Scenario:

I'm in the middle of drafting an email within Neos, but I get a call and have to source information from our environment. I am now required to either open an entirely new tab or delete my unfinished email just to search in Neos instead of having the option to minimize my email. This can be frustrating during busy work hours.
