Improve Preview in ExactScan

This is more of an ExactScan request than for DT, but here goes anyway:

I’d like to see better visibility in the preview in ExactScan when scanning using “line art” as the color. The previews are very faint with line art.

I’m scanning receipts using an Epson Perfection 4490 Photo. I prefer to use line art because the final scans are easier to read than gray or color. I also like to crop the receipt to just the area I need. But, the previews using line art are unreadable, much too faint to see the area I want to scan. So, I switch to gray, preview, select the area I want to scan, than switch back to line art for the actual scan. I’d love to be able to cut out the extra step!

Cheers!
