In the case of in-person selling, choose only the best and most valuable cards
Many collectors use binders with padded covers and acid-free binder pages to organize valuable sets carefully
Id also like the text box for zoomed in card text to be wider and/or taller, enough to fit more card text but not too much that it causes the different ui elements to overlap or not fit on the screen
