This feature would be more geared towards a reciter who is already a Hafiz. One issue they face is that they suffer from choice paralysis when searching for a portion to read in their daily prayers and ultimately resort to small cycle of verses they're comfortable with. Ideally though, huffaz should recite from portions throughout the Qur'an regularly in salat and not just places they are comfortable with. The recommendation would not just be a "random ayat" as random ayat are not suitable for prayer, rather a short meaningful selection with a contained message.
