- remove any indicators from the row
- use the secondary ALL CAPS action with vertical separator 

** Can we remove the "Yay!" from the default browser string. Replace it with something more internationally friendly: "Cheers."

What will clicking on the left hand side of the row do? (Will it be click-able or have any result)?

If the left hand side will have no effect on click, it seems strange to separate the left and right with a vertical bar.

How about making this a toggle button? That would show the is/isn't effect of the row and match cleanly with the remaining UI.

My comments in #6 and #7 don't work well if a dialog or wizard is necessary to change the default browser. Hector mentioned that in Windows 10 there are more steps. A toggle button would be weird in that case. So the button makes more sense.

aight, going ahead with

  | MAKE DEFAULT

then

bettes@: should both "MAKE DEFAULT" and the rest of the row be clickable in the not_default case?

also, do we _need_ to say "default browser" 3 times?

Re #10, my vote would be that only the button should be clickable.

Re #11, the old Settings page included it 3x so it's not a regression. I played around a little but couldn't find a nice way to easily keep the 2-line row w/ button pattern and avoid that.

It would be handy to know how often setting the default browser links out to external UI. I'm wondering if it would make sense to use the open-in-new icon on a two line row? My corp machines are controlled so I'm not able to change the default browser to see what happens.

>> should both "MAKE DEFAULT" and the rest of the row be clickable in the not_default case?

Just the button should be clickable

>> "default browser" 3 times

Not an issue for me.

MD Settings: drop subpage arrow from default browser section

Instead, show a "MAKE DEFAULT" button as a call to action so it's clearer
how a user can change their default browser.
