The Watchlist includes a "Mark all pages as visited" link that does just what the name says. We should
- Replace the existing link with one in the new style. See design below.
- Change the name to "Mark all changes as seen" so that the name matches the new "Seen changes" / "Unseen changes" filters in the Watchlist Activity group. T171127 @Pginer-WMF !![Unless we want to change the filter names?!!
**Question:** on the functionality: Say you're filtering for "Unseen." So the whole list is unseen. Then you Mark all as Seen. Does the page immediately update to empty out? If it's not too hard, that would be cool, not to mention consistent.
- The icon used is the "doubleCheck" icon used on the [[ https://en.wikipedia.org/wiki/Special:Notifications | Notifications page ]] for a similar purpose.
- The button will be shown as disabled if there are no pages to be marked as visited.
