It will be awesome if TOAD's Formatting for case conversion has more options. I have a style of writing SQL where KEYWORDS, TABLENAMES, COLUMNNAMES are ALL CAPS and Table Aliases are in lower case. I found Toad Formatter very useful, but if you can expand the identifiers to table aliases, column aliases and so on it will be very helpful.
Example SQL
SELECT
a.COL_NAME1,
a.COL_NAME2,
a.COL_NAME3,
b.COL_NAME1,
b.COL_NAME2
FROM
TABLE1 a,
TABLE2 b
WHERE
a.JOINKEY1 = b.JOINKEY1
AND a.JOINKEY2 = b.JOINKEY2
