Enable customization For 'FOR XML PATH'' on a different line.

This is how it looks in V7 formatting style:

SELECT PaymentIDs = STUFF(( SELECT DISTINCT
',' + iap.PaymentId
FROM TestDB2..TestTable2 AS iap
WHERE iap.LoadId = CONVERT(VARCHAR(50), trx.LoadId)
FOR
XML PATH('')
), 1, 1, '')
,CardholderName = CASE WHEN cdt.CHType = 1 THEN ISNULL(cdt.FirstName, '') + ' ' + ISNULL(cdt.Lastname, '')
ELSE cad.CompanyAccountName
END
FROM TestDB1..TestTable1 AS trx;

This is how it looks in V8:

SELECT TestColumn = STUFF(( SELECT DISTINCT
',' + iap.PaymentId
FROM TestDB2..TestTable2 AS iap
WHERE iap.LoadId = CONVERT(VARCHAR(50), trx.LoadId)
FOR XML PATH(''))
,1
,1
,'')
FROM TestDB1..TestTable1 AS trx

Using the default style with only the following adjustment:
CLAUSES
··> join
····> on condition
······> Place on keyword on new line := False

Currently, nested joins that are logically grouped with parentheses will format without spaces around the parenthesis, and all the tables are left aligned (example below).
SELECT co.Name AS CompanyName,
·······ct.Name AS ContactName,
·······ph.Number AS PhoneNumber,
·······addr.Address AS MailingAddress,
·······city.Name AS City
FROM Company AS co
····LEFT OUTER JOIN(Contact AS ct
····INNER JOIN Phone AS ph ON ph.ContactID = ct.ContactID
····LEFT OUTER JOIN(Address AS addr
····INNER JOIN City AS city ON city.CityID = addr.CityID)ON addr.AddressID = ct.AddressID)ON ct.ContactID = co.ContactID;

Removing the parentheses will format more nicely (example below).
SELECT co.Name AS CompanyName,
·······ct.Name AS ContactName,
·······ph.Number AS PhoneNumber,
·······addr.Address AS MailingAddress,
·······city.Name AS City
FROM Company AS co
····LEFT OUTER JOIN Contact AS ct
········INNER JOIN Phone AS ph ON ph.ContactID = ct.ContactID
········LEFT OUTER JOIN Address AS addr
············INNER JOIN City AS city ON city.CityID = addr.CityID ON addr.AddressID = ct.AddressID ON ct.ContactID = co.ContactID;

It would be nice if the same formatting would be applied with the parentheses included, AS shown below:
/*GOOD*/
SELECT co.Name AS CompanyName,
·······ct.Name AS ContactName,
·······ph.Number AS PhoneNumber,
·······addr.Address AS MailingAddress,
·······city.Name AS City
FROM Company AS co
····LEFT OUTER JOIN (Contact AS ct
········INNER JOIN Phone AS ph ON ph.ContactID = ct.ContactID
········LEFT OUTER JOIN (Address AS addr
············INNER JOIN City AS city ON city.CityID = addr.CityID) ON addr.AddressID = ct.AddressID) ON ct.ContactID = co.ContactID;

Better still is the option to place the ON clause for nested joins on a new line, AS shown below:
/*BETTER*/
SELECT co.Name AS CompanyName,
·······ct.Name AS ContactName,
·······ph.Number AS PhoneNumber,
·······addr.Address AS MailingAddress,
·······city.Name AS City
FROM Company AS co
····LEFT OUTER JOIN (Contact AS ct
········INNER JOIN Phone AS ph ON ph.ContactID = ct.ContactID
········LEFT OUTER JOIN (Address AS addr
············INNER JOIN City AS city ON city.CityID = addr.CityID)
········ON addr.AddressID = ct.AddressID)
····ON ct.ContactID = co.ContactID

Even better is the option to place the closing parentheses on a new line (with the ON clause), AS shown below:
/*BEST*/
SELECT co.Name AS CompanyName,
·······ct.Name AS ContactName,
·······ph.Number AS PhoneNumber,
·······addr.Address AS MailingAddress,
·······city.Name AS City
FROM Company AS co
····LEFT OUTER JOIN (Contact AS ct
········INNER JOIN Phone AS ph ON ph.ContactID = ct.ContactID
········LEFT OUTER JOIN (Address AS addr
············INNER JOIN City AS city ON city.CityID = addr.CityID
········) ON addr.AddressID = ct.AddressID
····) ON ct.ContactID = co.ContactID

When adding group by to a select, it would be nice if the TAB-to-expand-wildcard would only include the columns in the group by

Consider this Select:
Select *
from tblA as a
inner join tblB as b on b.fk_tblA_id = a.id
group by b.Value

Today expanding the * will give:
a.id
,a.value
,b.id
,b.fk_tblA_ID
,b.value

This is actualy invalid sql as only the columns included in the group by can be in the select.
Instead it would be nice if the first TAB press would give the columns in the group by, so in this example just:
b.Value

I often finde my self adding ", count(*) rowCount" to the select, as It is always nice to have an idea of the data size biehind the group by, so an option to add some extra sql to the TAB-to-expand-wildcard-when-using-group-by would be nice

With multiple tables joined in a select, make it optional to have multi level expansion

Consider this Select:
Select *
from tblA as a
inner join tblB as b on b.fk_tblA_id = a.id

Today expanding the * will give:
a.id
,a.value
,b.id
,b.fk_tblA_ID
,b.value

Instead it would be nice if the first TAB press would give:
a.*
,b.*
Pressing again without moving the cursor could expand all * to the same result as today, but if the cursor is changed to a specific *, then only that * would be expanded

I often finde my self joining 3,4,5 tables or more, and often just need a single column from the first and last tables
