After adding topics and creating your first watchlist (WL) you can easily change them and their viewing arrangement.
Here you can filter the results in different ways. They're mostly straightforward, but we have clarified some things in the link above the picture.
All your created WLs have a default name. However, you can change that.
Hover over the pencil next to the WL name with your mouse to rename a WL. And if you create too many, you can delete them with the trashcan.
Adding New Topics to Existing Watchlists
After you've created a WL, you may want to modify it or add new topics. To do this, click on the Add Topics search box on the right side:
You will get the same search box as when you create a new WL. You can add popular topics or search for new ones.
You can even add complex Boolean queries, like Google AND Apple AND NOT Microsoft.
Temporarily Hiding and Permanently Deleting Topics
If you temporarily only need news from specific topics but don't want to make an entirely new watchlist for them, you can deselect stories with the check box on the left side of the topic name. Or you can click on the three dots to the right and unselect from there.
Finally, if you want to permanently delete a topic from a watchlist, click on the three dots to the right of the topic name and then click Delete this topic from watchlist.
