Apple - Is there better third-party scanner software for OS X than Preview?

You may also want to look into the excellent VueScan. I haven't had a need for it in several years but back in the day it was really one of the best there is. Looks like it is still updated regularly.

PDFScanner from the app store is awesome. Very fast. Simple. Achieves small file sizes.

You might try Paperless. It retains the options across scans, and can do multi-page etc.

(And, relevant to the ADF):

• Paperless will display the Image Capture dialog.
• If the ADF is supported by Image Capture, the dialog will display Feeder as an option to acquire with.
• Choosing Scan will cause all pages in the ADF to be scanned.
• All scan jobs (multipage documents) scanned before choosing Done will be imported into Paperless as separate multipage documents.
