Some ideas

• Maybe add an option to star (⭐) a session and filter for anything starred. (Use local storage)
• Should two starred sessions be at the same time, and different rooms, highlight them (could also highlight if some could overlap with another starred session, since you have different stages and can run at different durations)
• relative time measure (in 15 minutes/Happening Now)
• filter by speaker name
