In the table creation step, how about having some columns with all the available options for each table field such as "unique", "required", "notnull", "nonempty" as checkboxes. The types could also come from a dropbox with: "string", integer", ...
I don't know if this kind of thing could be applied elsewhere but it would be great for those that don't want to know by heart all the possible options and apply them... Thank you, Best regards
