Please include an option to include the purchase details but NOT apply categories.
The critical information here has always been connecting the Quicken row to the items purchased. It's very valuable to me to know that transaction FQHDDDYBT was for a can of Pringles; it is not valuable to me to have it auto-categorized as "Food" instead of the "Groceries" category I actually use*.
(*As others have noted, Quicken is actually applying categories I have long since hidden and don't ever use; it's possible that if it exclusively applied categories I use it might be worthwhile, but it's still guessing wrong much of the time. Better would be as-is, including line item detail in the memos and splitting — but not auto-categorizing.)
