Our workflow is that we:
Press "Compose"
The default email address is an email from a shared inbox. It’s configured here: Preferences / Personal / Preferences / Default channel
We add participants
Then the draft is in the shared inbox and we see the "1" badge there. People almost always forget to assign themselves to this shared draft. So it lingers around in the shared inbox. It would be helpful if a shared draft would by default be assigned to the creator so that these drafts don’t pollute our "zero shared inbox".
This would be a truly helpful feature, as this creates more work for the folks who are doing our triaging to have to Assign drafts when folks forget to Assign to themselves. At the very least, the ability to be able to make this happen by setting a rule.
