The flow function is outstanding I use it a lot, but it would very helpful to have a button to send a partial screenshot to flow automatically, without the need to open the flow panel and paste it there after you press the copy button.
When you select an area to screenshot you see 3 buttons to cancel, copy and paste and capture, I suggest 1 more button to send directly to flow.
It would be useful when you work on more than a computer and is just interested in one part to paste, I use it when studying so I can create a summary with graphs and images and the feature would speed up the process.
