You can use a database to have all your pokerstars hand in order and for easy review. If your looking for a free one, try FPDB, its an old open source poker database that you can import your hand history for review. A little harder to use at first compared to the commercial one but its free.
The easier way is still getting a database like the one in the stickys, they do pay for themselves in the long run.
I use DriveHUD, but you can us any of the database you prefer, all the major database works in pokerstars.
