That is a really good point. The program doesn’t have an add/remove columns function because the coin grid has a column for every field, including user-defined fields. That is, with the exception of “Date purchased” as you pointed out. Since you can rearrange columns and adjust their widths as you wish, there’s really no reason to not just include all columns. Anyway, upon reading your post we set about adding a column for date purchased and that is now done on both the Windows and Mac editions. We’ll run it through some testing and the next update will include this column. Since it’s a brand-new column, it appears at the right side of the table but you can click-and-drag it to wherever you wish and it provides the same search and sort functionality that all the other columns offer. Thanks for the feedback.
