The SOQL editor has come VERY far since early versions of TWS but one thing still bugs me: if I check a field over in the schema explorer, it rewrites the query based only on what's checked in the schema explorer.
It would be very nice if this rebuilding of the SOQL looked at the existing text and only replaced the SELECT portion. That would allow me to monkey around with the fields without having to tdo the copy/paste dance on the rest of the statement.
