Have the ability to train intellisense when joining tables to learn which tables join together.

so that in the future you can just type:
"select * from employees e
left join "

and intellisense gives a drop down list of related tables, which when selected writes out the table name AND join columns.

i.e.:
"select * from employees e
left join "
and intellisense suggests: "manager m on m.managerID = e.managerID"
