Except, this doesn't enhance usability for anyone. The top level of the chart of accounts is how we have designed our own QuickBooks to show us reports. Neither my clients nor fellow accountants get any use out of having to constantly re-format our screens. If you must make the collapse/expand do it to the extreme - whatever - but then leave my custom expanding/collapsing to be memorized in the specific report until I manually click collapse/expand again. You need to roll back the update for now until you can make it usable.
