When deciding if a feature relating to the presentation of information is technical or not, what has to be considered is whether or not it contributes to solving a technical problem. The fact that mental activities are involved does not on its own render the subject-matter non-technical (T 643/00, T 336/14). However, a feature that solely addresses a user's subjective preferences does not solve a technical problem (T 1567/05).
For further information on the technical character of features relating to the presentation of information and display of data, see chapter I.A.2.3. "Aesthetic creations" and I.A.2.6. "Presentation of information".
