Tim, whether it is bug https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1187850 or this one, our objective or request is that a pagestack be implementable inside a tab. As you saw yourself, in the add city design, it is basically a new page, while the clock is in another page. Both these pages are housed in the clock tab. So it is necessary for pagestack to be possible inside a tab. That's what this bug is all about.
