To clarify for myself and potentially others (I had to re-read the proposal a few times to understand what was meant by "inline editing"), the proposal, as I understand it is (roughly):

Replace the inline expandable list of networks with a subpage.

Currently this is not a release blocker for MD Settings. Since there are no / minimal perforance benefits for Internet, this is not a priority for 58.

Tom, is this a Pri-1 for 58, or can it wait for 59?

59 seems reasonable.

Note: When this is completed, the VPN Settings button in the System Tray should direct to the VPN subpage ( issue 692334 ).

+ Instant Tether folks

I am going to knock this out for 58. The risk is pretty minimal, and it will improve performance. It is also going to block Tethering and other related UI soon.

 Issue 688271  has been merged into this issue.

This moves or shares some properties between internet-page and

from network-summary-item to a subpage.

There should be no functionality changes.

This CL also (finally) adds a few basic tests for the internet page. They are by no means exhaustive.
