What would YOU put in a Drupal 'cookbook'?

[Tony Horrocks]

I'm speccing out a project for people with basic CiviCRM skills. When I'm doing a dev project there's always a whole bunch of stuff I do for CiviMember because that's what I specialise in.
Without going into rocket science, does anyone else have what I would call 'cookbook' ideas for stuff that comes up time and time again?

Help very much appreciated.
