I would also like to know if you can hide or make a folder for applications you have downloaded so they dont show up in the big list where all the apps are displayed
or use a file manager of your choice and make a folder without quotes ".privatepics" and put your pictures you want to keep private in there - the trick is to have a "dot" in front of the file folder name
then to see the pictures, you must use your file manager and navigate to the picture you want and click on it - a pop up will appear asking what viewer to use - select and view your pciture
I downloaded "secretLock" and "Astro" both are free apps. I used the secretLock to password protect and hid certain pictures/folders. I used Astro so I could easily move pictures into one folder with other hidden pictures. It has worked great, so far.
