If I wanted to add 4 fields to hold additional data on a production season.... is the best practice to create a new table and add a form to the custom tab or creating a new field in tkw to house that data?
My concern is using the content tab for something that it is not intended to do which will eventually come back and bite us.
What are your opinions?
You should definitely never add to or modify a Tessitura table, so I would strongly recommend a custom table (full disclosure, I've made scores of them over the years, so perhaps I'm a little to trigger happy).
Why wouldn't you create four content types and use those with the production seasons?
