Luci default tab/node

When I was using the default theme, typing 192.168.8.1/cgi-bin/luci/ took me to 192.168.8.1/cgi-bin/luci/admin. Now I am using Freifunk theme and it takes me to 192.168.8.1/cgi-bin/luci/freifunk (see the following screenshot)

This gave me some idea to play with adding new elements to luci interface. I followed https://wiki.openwrt.org/doc/devel/luci and added a similar 'new tab' node for testing purpose.

module("luci.controller.myapp.new_tab", package.seeall) 
 function index()
     entry({"new_tab"}, firstchild(), "New tab", 1).dependent=false  
     entry({"new_tab", "tab_from_cbi"}, cbi("myapp-mymodule/cbi_tab"), "CBI Tab", 1) 
     entry({"new_tab", "tab_from_view"}, template("myapp-mymodule/view_tab"), "View Tab", 2) 
end

Everything is working perfectly. I just want one more thing. I want to load This New Tab node as default when I type 192.168.8.1/cgi-bin/luci/ (The same behavior which is being shown by Freifunk) How can I achieve this?
