Hi
Thanks a lot for this plugin, my metadata searches are a lot more effective now

I have one small polite request: would it be possible to have an option where if the extract process doesn't find isbn, that it adds 'not found' in the ISBN column. I keep forgetting which ones I have run the search on and which ones not.
In case this is already an option that I didn't find, my apologies and please be so kind as to point me in the right direction
Thanks a lot
Maarten
