Hi,
I would like to make a feature request. Given that each page is linked to a Pick Type number (Eg: P# IND25), I was wondering if it was possible to insert links to each Pick sub-type, in the sub-types table (image below)

In the above table, we see 4 sub-types of Pick IND25, namely: 25a, b, c & d.
It would be helpful if each description of the sub-types (after the'frequency' column), were to link to a pop-up page/div that hosted the obverse and reverse of that sub-type.
The advantage gained here, is that every Pick sub-type has a dedicated and detailed photograph as a reference. The main photograph at the top of the page will still remain though as it should represent a typical-to-type photo of the note.
Being from a web application background (Java, Oracle, Apache etc…), happy to discuss with your developers to help design and implement this solution.
