Better slideshow solution than Apple built-in Photo, could use a few tweeks

Better slideshow options and functions than Apple Photo built-in app, works as stated worth the purchase.
Suggested improvements:
1) allow slideshow to mirror when using airplay, currently only on iPad display or AppleTV display. I would like to have displayed on both using mirroring as a 3rd option.
2) Need a way to select complete album of photos in Photos library, right now you have individually select each photo. Real PIA.
3) Have option to use the detailed face detection by default for all photos. And have option to search even deeper for faces.
