Feature summary (what you would like to be able to do and where):

I think it would be useful to display a success message after creating, editing or deleting a watchlist label, for example:

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

There is currently no feedback to show the user that the operation was completed successfully.
Since the labels are sorted in descending order by the amount of items by default, newly created labels appear at the bottom of the list, so users who have many labels currently have to scroll down and look for the label to confirm that it was actually created.

Benefits (why should this be implemented?):

Users would receive feedback this way after performing the action.
