I'm running Curse of Strahd and I like the book's suggestion to use milestones instead of tracking XP. It provides a list of example milestones, but it doesn't seem to include everything. Has anyone seen any official or (more-likely) unofficial lists of suggested milestones that are more exhaustive? Or, do you have any suggestions or plans for what you'll use yourself? I've played a lot but I don't normally DM so I'm a bit concerned with levelling the players too quickly or slowly.
