The Screenshot tool has a usability weakness that can be solved with 1 button.
When framing a screenshot, the buttons Capture and Cancel appear.
Add a third button, "Copy + Close" alongside the other 2 buttons. see new button (image)
This saves users going to the second screen when it's not always needed. Important when lots of screenshots are needed quickly. Many other screenshot tools have this fast copy in one click feature.
The current Capture button would need to be called "Edit Capture" as it takes you to Edit!
