I know the frustrations about the titles. Once you get a handle on scripting, the frustrations go away.
The script that Leone provided, that mass updates the titles, works very nicely. I took this script and added a section that automatically creates "day" albums to mimic the old "events", and then creates "Month" and "Year" folders to mimic what I did in Aperture. And I am not altering anything with the normal Photo container that is organized by Years/Collections/Moments. I use this script to process all photos after importing.
The apple automator is extremely powerful, and it lets you do whatever you want. Once you get comfortable with scripts it opens up a whole new world, where you are in control - and you are not dependent upon the vanilla software. Leone provides directions on making the script a service that can be called from the Photos pull down menu.
