Download notification goes to Min, I think.

For regular download,we have the remaining time and percentage text on the notification. 

If we choose to use "Downloading...." text, are we going to drop the percentage text? 
And I did not see the remaining time/percentage text in the UI mockups, seems the mockups only matches that of the offline pages.

Fyi, I am seeing odd notification UI currently (at head). Perhaps still in progress but wanted to mention it.

1. For a pending web page download I see "Downloading..." string with indeterminate progress bar.
2. For an active web page download I see "Downloading..." string with "0sec" remaining but no progress bar.
3. If I have one of each and swipe away Chrome, then I see "Download pending..." string for both.

John, looks like this bug is pending on you for clarity per comment #5 from Min.

My understanding for offline pages where we do not provide a percentage progress, we should have:

1. For scheduled/pending:  "Pending..." string with no animation
2. In progress/offlining:  "Downloading..." string with indeterminate animation (for web page) [and determinate progress bar for downloads?]
3. Swipe away Chrome"      "Pending..." string with no animation

Does that sound right?

In comment #7 above I note what I actually experienced. I think the "0 secs" is not longer displayed more recently.

Dmitry opened bug on the 3rd case here: https://bugs.chromium.org/p/chromium/issues/detail?id=667011

Comment #9 sounds right to me. 
BTW, a CL fixing #1 and #3 is getting landed: https://codereview.chromium.org/2514783003/

I think there still are some issues getting to the UX for web pages.

#3: [chrome killed] I checked again with Dmitry's patch and it does remove the indeterminate progress for the case when you swipe away chrome. However, the icon is still animating which does not fit the UX deck slide #5 text description: 
  "While download is pending, we won’t animate the icon in the status bar."

#1: [scheduled] Still showing as "Downloading..." for me rather then "Download pending..." and still showing indetereminate bar.
#2: [downloading] Still does not show indeterminate progress bar.

I think 1, 2, and most of 3 in comment 11 are now fixed via blocking  issue 668231 

What is still not addressed is that the icon is still animating for the pending case.
