What steps will reproduce the problem?
(1) Start downloading a media file (e.g., an MP4 from https://www.ssyoutube.com/watch?v=OLuq3CKqky8)
(2) Either manually pause the download (via the Android notification) or disconnect from the network, causing the download to auto-pause.

What is the expected output?

In-progress and paused downloads should be seen in the Chrome 'Downloads' menu. That menu should show the state of each in-progress/paused download, the total size, size downloaded, time remaining estimate, and options to pause/cancel/resume as appropriate.

What do you see instead?

What we seem to be doing currently is relying on Android notifications for showing the status of in-progress downloads. This has a number of usability problems:

1) A user who receives many notifications (e.g., from messaging apps, etc.) may lose the download notification.

2) Apparently, swiping away a notification for an in-progress or paused download is equivalent to canceling it altogether. There is no way to get back an in-progress download if the notification is dismissed. (Problem #1 described above makes this much worse.)

3) UC Browser has a much nicer UI for managing in-progress downloads; we should strive to be at feature parity here.
