Estimates in QuickBooks online using the mobile (smartphone) interface.

I have a construction client who wants to move to QuickBooks online.  The purpose of this is that he doesn't want to be tethered to a computer all the time, and be able to run most of his business from his Blackberry or Android smartphone.  I've turned on the estimates feature, and it appears to work fine when logged in from a PC.  However, I have not been able to find the estimate function when logged into the mobile (smartphone) site.  Am I missing something, or has Intuit really not added this?  The client is not large enough to really need a full job-costing system, and has used classes in the past (before adding me as his CPA) as a workaround, so they're ok with not having full job-costing functionality.
