Does track the specific device that last updated a record

Round Tripping from beta 8 2014  http://www.timdietrich.me/blog/easysync-beta-8-released/

(One possible solution - and perhaps something you'll see in a future version of EasySync -
is to add an additional EasySync field that will track the specific device that last updated a record.)

Has this been done or are we still round tripping as noted in the link above?

I have two versions of client:
1.  Data Entry Only 
2.  View Data Only

When they are run on the same iPad and data is entered with Data Entry Only and Sync'd all is well.
When View Data Only is used on another iPad the data sync's nicely.

But, When View Data Only is used on the same iPad the record previously entered with the Data Entry Only database
does not appear in the incremental sync.  It will appear if I Reset ( with sync utility ) in View Only Data, then Sync.

Not quite sure why the reset should enable the iPad to get the record, unless the reset changes the devise id or something.

Any explanations are most welcome.
