So does anyone know how to make the .thumbnails folder invisible in the Pictures app and the file picker dialog? I find it most annoying to have duplicates of every photo in the "All Pictures" album and in the file picker when trying to upload photos to a website or attach to a tweet. I invariably end up attaching or uploading the thumbnail file instead of the original image.
Also, if you have a movie loaded in the videos folder and then later delete it, the thumbnails remain also.
Also, is it just my imagination or did all these thumbnails only start getting treated like regular images with the OS2 betas?
