You can also take a look at this for an example of how to reorder extending views: http://community.elgg.org/plugins/1520344/1.0/group-tools-priority
You can always use elgg_unextend_view() to remove the views that you do not want to display.
What am I missing? Are you still searching for the physical location of that view or not?
If you have the shipped plugin 'developer tools' installed, just: develop: tools > inspect >views (submit) and then scroll down untill you find 'groups/tool_latest' click the little arrow and see where the physical view (or views if others are extending or overriding) is.
And you can always add the view to your own plugin if you really want it to have a physical location. You can then put your logic in there. But as Pawel suggested, you should really read up on the Elgg's views system. It's the pillar of Elgg, and if you don't understand how it works, you will have serious trouble moving on.
