Because I extensively use the new Inbox by Gmail, and it's feature to bundle certain emails in my inbox once a day/week, but I also still use the standard Gmail, I like to see what's really in my useable inbox (that's not in one of these bundles) by this search:
has:nouserlabels in:inbox
Is there any way to get a link to this simple search as an option in my label list on the left, or even to replace the Inbox option with this one?
