Adwaita doesn't have curved tabs.

Yeah, I'm not gonna add this, because Adwaita doesn't have curved tabs, and I don't even know how to make it look like that. You can add curved corners at the top of the active tab like this:

.tab-background[selected=true] {
	border-top-left-radius: 10px;
	border-top-right-radius: 10px;
}

But I don't know how to make those curves at the bottom and it probably wouldn't work with this theme anyway (because of space between tabs and border-bottom of the active tab).
