Hi there!
I understand that you want to make some changes and improvements to QuickBooks Online to meet your business needs. The more feedback about a certain feature our engineers receive, the bigger the chance it'll be added.
Also, you'll want to visit our blog. From there, all our innovations will be posted. If you need articles and references in managing your business, you'll want to check our QuickBooks Help.
Keep on posting here if you have more questions. We'll respond as soon as we can.
