I use the capture window all the time. A critical part of my workflow.
But I don’t always send the text to Drafts. I often use it as a shelf to hold and refer to or copy and paste elsewhere.
I’d like to suggest adding a button to the bottom menu titled “Copy & Clear” or “Copy & Save” or both or give the user the choice to add these buttons show on the menu…
It depends from your workflow. I would be happy with a copy button. But the clear function would be annoying for me. I would prefer to clear the capture window manually.
