We're shortly adding a "play more tunes by this artist" button, though this works by scanning the rest of the current playlist and moving tunes from the current artist to the following play positions (trust me, it works) - jumping to a playlist is hard, as a tune can be in more than one playlist, and there is no "preferred" parent.

Bookmarking of playlists is coming too, allowing you to save your playlist (and position) - good for things like switching between an audio book and a music playlist, or different drivers of the car having their own saved position.
