In the current web client (flash app) kibitzing a single hand is selected through "Options -> More options -> Advanced Options". But generally speaking "options" refers to permanent selections like the font sizes, sound and so on. I don't think a transient selection like which player to Kibitz should go there.

I'm not sure how difficult it would be, but I'd like to propose moving this option to the subwindow you get when clicking on the player at the table (showing their identity, convention cards, etc). It would also be great if you could incorporate the functionality in the mobile app.

try right clicking the name of the player you want to kibitz while at the table. you should see a pop-up menu that lets you watch just their hand (even rotates the view for (in)convenience).
