Currently interaction log, comments and tasks are rather hidden and to get quick overview it requires few clicks to get quick overview. Sales cycle table takes 50+% space from the Opportunity page and it would be rather better do have comments, tasks, interaction visible rather than just log of sales cycle (for sales cycle you dont need more than just one cell displaying cell or Kanban as some proposed).

If working with 100+ opportunities it takes massive amount of time to get quick overview of latest activities related to opportunity.
