Interesting, but bikeshedding. Just use capitals and/or quotes. Nobody is getting confused by something like:
Would you like to share the 'My Pictures' folder?
Would you like to share the 'My Pictures' folder?
‘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.
