It would be wonderful to have recents added to the drop down when you click on Family Tree!
It doesn't fit.
Recents is a drop-down list. Everything in the top menus is a link to a page. They'd either need to come up with a full-page version of Recents, or they'd need to completely revise the navigation of the site. A full-page version of Recents would be a clunky and unnecessary waste of bandwidth.
The new home page does put Recents in the second menu bar for easy access from that page. This full page version does load quickly and it's kind of nice that it just sits there. You can leave it open in a tab and right click on a name to go the person's page in a different tab. On my screen I can see thirteen names at once rather than the seven in the drop down menu so there is less scrolling to see the entire list.
