New tab colors was much simpler than it appeared. I only had to update browser compatibility since the properties are already defined as a result of Chrome support for them.

Example added as well.

Asked about this one: #1470516 as I'm not sure that it needs anything but a release notes comment because none of the existing documentation says anything about localized strings.

Remaining DDNs:

1347207 should be done today. 1418602 asked what changes there are to document here. It isn't clear from reading the bug whether theme creators have to define something in particular to have this work. 1280370 should be done this afternoon. 1396684 This one may not be done until tomorrow (Friday) morning. 1369209 Another one that may not be done until tomorrow (Friday) morning.

1369209 - Some of the information in the bug description implies that the management.install method only applies to lightweight themes. It doesn't seem to make sense to document it if LWT is going away.

[irenesmith]

1347207 - Removing this one from the issue as it is more extensive than a DDN. I will discuss the subject of experimental themes with the team and determine how ready it is for release, then come up with a plan to document it fully.
