My Ubuntu MATE 22.10 went through some sort of version update, during which Evolution was deleted. I added it back, and all my settings and offline messages are still there.
The new version adds a header bar; I'm unemotional about it, neither pro nor con, I'll use it. However, when I reply to an email or create a new one, the message window does not display a Send button; it doesn't have a header bar at all. The send option is available under the File menu. I Googled and found some screenshots in which the send button is shown, but I don't see any setting in the message window menus to toggle on the header bar or show the send button.
Is there any way to get the send button back? Since this is such a common action, having to pull down the menu every time is a nuisance.
