While not blocking at all, I noticed some small iprovements could be made to the buttons in the Update window.
When you click the Pause button, it would have expected that the button turns into a ‘Resume’ or ‘Start’ button, but it remains a ‘Pause’ button.
When the update is complete, I would have expected the Stop button to become a ‘Close’ or ‘Exit’ button.
As I said, nothing blocking, it would only make the UI a little bit better and easier to use.
