If you're looking at a view, for example in the Basedash demo "[Demo] Users with verified email", and you are adding a new record, if you are selecting from a column that is represented by a foreign key, in this case "Company", it opens a select style box where you can choose a record from the joined table. It would be handy if a new record could be created in maybe a little modal window or something so users don't have to go to the company table/view and create it first. Particularly useful for users not familiar with SQL and foreign key constraints.
