Hidden Secret Folder feature...
Nothing says "I'm hiding something! Come on in and Look!!!" quite like a folder called "Secret Folder"...
... but you can rename it! Once you are in the secret forlder, click on the top where the words secret folder is... just to the left of the lock. Then rename it to whatever neutral name you want. I doubt anyone will go trying to break into my "Work Backups Folder" No one will even wonder what might be in there.
A second tip I found... It might seem like a pain to have to find the folder, and unlock it, then go into it... blah, blah. You can select a item in the secret folder, hold it, and then drag it to the top right "add to home screen" It will then add a icon to the home screen that will be locked when not in use. So you can jump directly to the secured app you might want, without the need to load up the folder in general. I then added those links to my "tasks edge" panel and removed the original from the home screen.
