No indication in the sidebar for ongoing file operations beyond the max number displayed
When there are more than the limit of ongoing operations (4) there is no indicator, label or other feedback that there are additional operations happening--those can only be seen if the popover is open and scrolled--so an overflow indicator is needed here.
Solution
A way to solve this would be to have another item in the operations list that states the number of additional operations beyond those seen and is present as long as there are more than the max number operations occurring and decrements as operations complete and clear the list.
- the design treatment in the mockup is a string with the number of operations and "more..." and it uses the progress ring in an indeterminate state with a more icon within it
