What I can see comparing features quickbooks online global VS qb online us/desktop is that developers are not paying attention to all features that could, for sure, bring more customer base to global version.
Not only this simple feature (which is just adding CLASS to groupby/filter to all possible options), but others like USERS having more specific restrictions (like US version)
So yes, your company always say to send developers feedback, yet they never work on it and/or do not care - at all.
