How to change "page_stream" for endorsements page?

I am trying to make some minor changes to how the Endorsements page displays endorsements.  I am trying to figure out how to , for example, expand the maximum number of lines displayed (before "show all") per endorsement, how to add Occupation/Title after the name or the endorser, and how to change or get rid of the "Showing 6 Reactions" and "Following Reactions."  These features all seem to be embedded in the single html statement in the page theme: 

    {% include "page_stream" %}

Can you telll me how to get at "page_stream" and what sort of changes I should make to achieve my goals?

Expand batch update tool

You provide this great Batch Update function under Lists.

It would be a big help in efficiency if that were expanded to allow changes in most other fields, e.g. City, Country, Employerk, primary contact.

The method of uploading, editing in Excel, and downloading is cumbersome and seems risky, too.  Please consider incorporating this directly into the NB toolkit.

Storing skills and association information on volunteers.

NB has fantastic tools for communicating with and keeping track of volunteers, but I have yet to find a place to record information on, for example, special skills, community associations/memberships/positions, and other information which a volunteer coordinator might know, but is not necessarily suitable for collecting through a survey.  Generally this information might fit better as notes than as tags, though it would still be nice to be able to search/filter on it.  Does this exist on NB?  If so, how is it accessed, and how can I search on it?

To search for specific information, you would use tags. A private notes feature to add additional information is also included on each profile in the dashboard. Notes can also be uploaded when you add people to your database. Private notes are not searchable.
