[Q] Stock Android Email client - force to show Archive button? topic

Does anybody know how we could force the stock android email client to show as much buttons (but especially the "Archive" button) on the top bar next to the "Trash" and the "Read" button?
It has more than enough space there, so no need to hide actions behind the 3dot menu.

It briefly shows up when opening a new email from the notification area, together with the create email big round button on the lower right, but it will disappear after a few milliseconds to hide in the 3dot menu. I tried to play around with DPI settings, but no luck.
Why is the app behaving in this apparently stupid way?

Thanks for any input on this!
