Personally, I was already aware of the heart distinction at the single level, but if you can't see at a glance then it's a terrible system for huge amounts of photos.
I have been accruing photos/pictures/screenshots on my device since my iPhone 3gs days and have amassed over 5000 pictures.
I should trim it down a bit, but I like having all of those picture local on my phone.
So, any method that requires looking at an individual picture is pretty much worthless and Apple really should have given us better.
I'm not saying that your information isn't good to know, I'm just saying that such any workaround that requires looking at single photos just doesn't scale to thousands of pictures.
Personally, I think we should all tell apple how displeased we are with their terrible changes at https://www.apple.com/feedback/iphone.html as I plan to do bi-weekly.
It might not fix anything, but then they'll at least be aware that people are really displeased with the change.
Though, that page only shows iOS up to 7.1.2 currently. I don't know if there is a better feedback page.
I understand why they got rid of the separated views. Clearly they are trying to either cut down on space used in iCloud or to try to move us to paid storage, but this is a pretty shady and consumer unfriendly way to go about it. They could have just lowered it to 500 if they really wanted to save on storage. I'd complain about that too, but I'd get over that pretty quickly and at least that wouldn't keep me from updating my devices.
Personally, I'm keeping all of my devices pre ios8/yosemite until they fix this.
If they don't then, I guess I'll upgrade when my 5s or iPad 4 are 4 years old and out of support, but not a day sooner.
