Nice @Antreesy, I have a couple of points:

• could we use content-copy icon?
• could we move both copy actions below every other action, just above delete?

Did already, forgot to update screenshot

• could we move both copy actions below every other action, just above delete?

If you think that would be better, sure, but with separator
We have also unread, forward, translate, and unknown amount of integrations buttons

unknown amount of integrations buttons

Could we put those in a submenu maybe?

Maybe not in RC stage but can do it later on.
