To answer your questions: yes, yes, yes, yes, yes, (however, I don't consider scanning ever a waste). Yes, yes, yes, yes, yes, yes, yes, and no.

May I point out that if you collect mint condition LE's, then it doesn't matter who's scan you use. Also, you may want to use the scans I provide until you get your own scanned. Then, you have a picture to have within the item. You can add a check box field with the field name: Borrowed Scan. Then you have a record of if the scan is your own chip or not.

Sort functions are numerous, and very intricate. You can sort by not only =, but also , Not=(not sure where my symbol is), quick searches (you can even save 10 quick searches) and then the simple searches on the tool bar. Searching and sorting is one of the best things about this program. Believe me, you'll be hard pressed to come up with a function this baby can't do. I have been told it even cures sexual dysfunction and acne.
