Tom, please make me owner if you'd like this to happen.
It will require a merge into m62 as we are past the m62 branch.

Tom, also see email thread "Moving part of OnStartup back to basic page".

Yes, let's merge this into M62.

Note that the change was made in M61, so we are acknowledging that users will see:
M60: top-level
M61: subpage
M62: top-level (after this merge)

That doesn't sound like a great user experience since we are planning to change the UI again* (likely in m63).

*because having this UI at the top-level recreates issues that were being addressed by moving it to a sub-page, so we'd still need to address dynamic content changing the page while the page is opening.

*because having this UI at the top-level recreates issues that were being addressed by moving it to a sub-page, so we'd still need to address dynamic content changing the page while the page is opening.

Understood, but from a user's perspective, I think the benefits of having their basic controls accessible on the top-level is more important than the dynamic content issue.

[MD settings] move on startup UI from sub-page to basic page

This CL moves the OnStartup UI from a sub-page back to the main (basic)
page. This essentially undoes (revert) CLs 557971 and 582467 while keeping the interim changes/fixes.

candrada@, to be helpful: here are some pro / con topics for merging this CL:

pro:
- UI change desired by UX (bettes@) and PM (tbuckley@)
- scottchen@ reviewed this CL with the knowledge that this was intended for merge (and was asked to be extra attentive to it for that reason)
- This is a self contained CL and the prior code and this code are both reasonable to ship (so there's a solid fallback/rollback option here).
- No features change (only moving existing features around in the UI)

con:
- No features change (the last to 'pro' is a 'con' depending on one's point of view).

Thanks for confirming and providing more context. Can you confirm if this is already tested and verified in Canary?

I can say that I see the change in Mac OSX chrome 63.0.3212.0 canary. (though it would be great to get it independently verified).

Can someone from QA weigh in on "tested and verified in Canary?"

Confirmed over chat that this is tested in Canary and there is a quick revert option (if needed). Approving merge to M62 (branch: 3202).
