Not sure if this goes to the right place for feedback since this is a community forum (of users), but there are QB people here who respond and will tell you where to send feedback.  I looked at the attachment you sent and would like to try to help with suggestions if I can.  I am curious what you are using that would require more characters than those.  Can you share any examples with us? 

For example, for Accounts, you really only need 4 digits if you setup right, give you 9999 accounts.
