Custom database fields

Knask good, but lacks the ability to add their own specific fields.

Henady, I may be confused by your issue--- but that is a core feature of what knack is built around-- a custom database that allows you to create your own fields and much more... ?

Bank = create a short-text field

city = could use the address field etc..

For example, I need

details of payment (Current Account, BIC, Bank, City, correspondent account)

Do you have a question? What sort of fields?
