We have added numerous columns to the Opportunity table, and ultimately I want to add a new table tying to the Opportunity to extend additional Opportunity Details into. Using the Advanced customization wizard as I am finding it the optimal solution, as from my experience it makes the new entity a one to many set-up, and I only need a one-to-one table, that doesn't need communications, or workflow, or anything else that the wizard sets up for you. I want to put this table as a new tab under Opportunity that doesn't lead to a list rather directly to the table with change screen capabilities. Is this even a possibility?
