Thanks to everyone involved for a great update! I have a couple of questions:
1. I want to record when I finish reading a book, so I created a user-defined column called 'Read' which is a date type using the default format. Once I have entered a date in the column, is there any way of deleting it?
For built-in date fields, this hasn't come up because there is always a date of some sort. But, for a "Date read" column, I would like to be able to delete dates entered in error.
2. Is it possible to search for books with an undefined read date? I've tried true/false and < without success.
Thanks in advance.
