StackInbox

Preserves new Stack Exchange Inbox messages until they are actually read. Items appear in the global inbox as they normally would, but the only items marked as read are ones that you click on. If there are unread items in the inbox, but you've viewed the inbox already, the unread count is displayed in blue instead of red. This Chrome Extension was inspired by a Meta Stack Overflow feature request: (http://meta.stackoverflow.com/q/72440/155826).

Because the development team is interested in avoiding bloat, anything that adds user preferences to the system or that adds more complexity is avoided. Thus, this extension gives this functionality to those who want it.
