I have the same issue. Our airtable base has a lot of nested and interelated tables. Its very usefull to be able to click through a record and then click on anouther linked record to pull up a drawer in the airtable interface that allows users to make changes to that linked record.
It seems that sometimes there is a way to reuse the forms or record details, but a lot of times the list of forms and detail pages is empty and you have to make a duplicate form. It would be great to see a complete list of forms from the entire base. I'm not sure how the list of forms is populated, but right now it seems pretty random.
