This is pretty good in a number of ways:
1) It’s not a memory hog
2) It asks if you want to delete whatever you’ve imported
3) You can have folders inside of folders
The bad thing is that you can’t really scroll easily through your camera roll. Say like you have 100 pictures in your camera roll and the ones you want to pick are offscreen, if you try to scroll it selects the photos where you are sliding your finger. Then you can go back through and unselect them the same way, then you try to scroll again, & then it selects them, then it decides that you want to scroll, then it scrolls. I’ve tried scrolled on the far right of the screen, far left side of the screen, in the middle of the screen, between the photos. It does matter. I’ve tried on both an iPhone X & an iPhone 7+ and it acts the same...
