How can disalble the display function of workitems?

[Kim, Go Joong]

Dear workflowers,
 
I like to listen your precious opinions.
There are many function buttons like as 'execute', 'display', 'preserv' etc
in the business workplace inbox.
How can i display the 'display' function button?
My customer wants to only use 'execute' button not 'display' button
because in the display function, someone can do additional actions like as
create attachments etc.
 
I'll appreciate your any comments.
