Well, all these ‘wtf does this icon mean?’ is about VSCO’s nature. They always stood out with that weird UI and actually that’s why they have their large community. It is fancy to be weird. I absolutely agree with You that sometimes scenarios they offer are insane but I love this app nevertheless. And as I know they are the first who implemented RAW feature.
Edit mode screen is customizable. You are free to keep that Filters / Edit features you only need. Icons without labels becomes familiar after 2 times you use them.
But Home Screen is something, that’s true:)
