Same here - all assets that are specific to a program are kept within the program (every program of ours has an "Assets" folder (emails, landing pages, local forms), "Reports" folder and a "Campaign Flows" folder (smart campaigns that move leads into specific program statuses and other automated flows). Like Matt said, most of our forms are used across multiple programs. Therefore, we have specific folders in Design Studio for these (e.g., "Gated Content Forms"). Same with our tokenized confirmation/operational emails - those too are kept in Design Studio.
