I would like to change the navigation items in Salesforce1 to standard objects such as Contacts, Accounts and Opportunities.  I can achieve this using a Flexilbe Page, but there are some limitiations that I am not clear on.  I also want to have Dashboards and Chatter available.  I would like for Chatter to continue to be the landing page.  My two questions are:

1. Will Dashboards and Chatter be available in the main navigation items?
2. If they are not, do they get demoted to Recent or do they not show up at all?  It looks like it only shows custom objects in Recent Items

Based on what I read below, I don't think that I can do what I need to do, but wanted to make sure that I understand if that is really the case.

Available Components
Not every component can be specified in a ComponentInstance. Even among those that are allowed, not all of their attributes can be specified. Currently, two components are supported for use in Flexible Pages.
flexipage:filterListCard
Points to a list view and displays the first few records from that view.
The flexipage:filterListCard component supports only:
Custom Objects
Account
Campaign
Case
CollaborationGroup
Contact
Contract
Lead
LiveChatTranscript
Opportunity
flexipage:recentItems
A list of most-recently used items which is limited to specific custom objects, based on the properties specified.

Tell Me More: Flexible Pages
When working with Flexible Pages, keep in mind:
A Flexible Page region can contain no more than 25 components.
The flexipage:recentItems component only supports custom objects.
