+CURRENTLY DOING: 
 
-issue: serials probably shouldn't be a free-form text box or stored or handled that way but instead as a list like tags are at the back end 
-	and in a list control at the front end
-	UI: 
-		entry mode
-			table below a single entry box
-			click on a row to edit in the entry box
-			click on a delete button to remove an entry
-		display mode
-			shows as a table
-			maybe don't need modes, can just use the same ui to view and edit and just remove the edit bits if readonly
 
-todo: make sure serials are de-duped at the server anywhere it accepts raw serial data from client
-
-todo: picking from existing serial numbers for parts on workorder
-	see work order item parts for notes and what to do
-	close 3839 when done
 	
 todo: as part of duplication above, REMOVE TEMPLATES ENTIRELY??
 	If can duplicate this way at client and can easily change customer etc do we even need the wo templates anymore?
