Bump from the dead. I like the PDF export feature, but would love a tab-delimited or CSV (or XLS) export that includes all the collection data (acquisition date, price paid, etc.), art data (size, run size, series, release date), and a little price history data (say, just original price, 6-month average, average, high, low?).
edit: And I'll add, I probably have enough DB knowledge to lend a hand if I knew the data structure.
