Hi David,

I love both your suggestions. They will improve the user experience greatly!

I think you would need to file these suggestions on bugs.kde.org in order to have them implemented.

Over the past week, I've relaxed that number and somewhat randomly added addl matches. Then I'd go back to a more sensitive number.  Rinse and Repeat.  I've now done this probably 20 times and it feels like I'll need to do it another 50x before I get to the point where we capture most of what we want.

When the results are presented to the user, it would be very helpful to allow us to sort by that score or scores.  That way when 1000+ results are displayed, we don't need to hunt for the good/obvious matches (or similarly, reject the blurry unrecognizable ones).  That would be an incredible time save to users who are trying to process a lot of data.

Correcting via ^Z doesn't seem to work (or if it does, it isn't obvious to me).  I'm especially concerned about the false positives.  I don’t know if the Digikam saves date/time for each recorded recognition, but if so, sorting on that would allow the user to correct mistakes much more easily.
