Agreed; if I’m writing help text or instructions, regardless of the use of “my” or “your”, I put pages or features in quotes or bold or italics or whatever format helps it stand out.

‘Click on your “My Cases” tab’

‘Click on “Account”’

etc

Reducing my/your in features is a good start (My Pictures → Pictures, as mentioned in this thread), but always treat specific concepts as proper nouns.
