  • Session title
  • Speaker name
  • Tags

We still need to group by timeslots.

[peirix]

• Add track number
• Grouping by timeslot
  • Lyntaler should look like "that"
  • Fellessesjon should look like the other one

[alexyork]

We now group by timeslot.

I also show the track, start date and end date on the session list page.

Done.
