Google+ Checkvist community posts 2013-2018

Managing a HUGE vist. What I'd like is a way to link items together, so I click on a link and it exposes the other link on the list, not opens a new page. Is there any way to do this?

It would be great to be able to see the parents of a line item on the due screen. Either via a keyboard shortcut, or show inline on select. Something to tell me wtf a particular due date is about.
