Is there any app that could help me rearrange my gallery pics and videos the way I want?... I mean the more pics I have the more chances the pictures I want stay at the buttom and scrolling all the way down to edit, delete, or use that specific pic as wallpaper seem kind of bothersome... I would appreciate info about an app to place my favorite pics and vids first on the list and place them by colours, date, and/or type. Thanks!
