Native OCR support would definitely be important to have.

Hi, many thanks for the request!

I've added this as a feature request: Provide OCR capabilities when importing a PDF

I agree that native OCR capabilities would be indeed very useful. However, depending on the license and/or pricing of the OCR library or service, this may be tricky. It's definitely something that won't come soon.

For users who also use DEVONthink Pro, this app supports OCR and could be used as a workaround.

What if the PDF has no text layer?
How would you highlight a section?
Could you still create an excerpt of the text?

If the PDF has no text layer, then one wouldn't be able to select and highlight (or copy etc) some text from it. Any app w/o built-in OCR capabilities has the same issue. There are tools that can run OCR on a PDF (such as DEVONthink), and these could be used as a workaround to preprocess the PDF.

Built-in OCR capabilities are certainly highly desirable, but it's not a small feature that can be implemented quickly.
