Ideas for improvement!!!

Hi,

I'm a proud user of almost all Mac products and there are 2 ideas I believe can improve the usage:

1. In find my iphone: It should also work for the mac book and you shout be able to delete all your passwords from the computer. I always save the passwords into the browsers and apps, etc. But what if it is stolen?? The most important thing we have is our information, and saving the passwords might be risky for that.

Another think I had always though regards the security is that the find my iphone app is not that accurate and good, once someone stole my old iphone and in Latin America that's something VERY common and I found it for a few seconds, but still couldn't find it. It was terrible to see the flashing point on the map and couldn't do anything. It shout have a chip or an app that can actually blocked complete the phone or computer, and only the owner could turn it back on again. So people stop stealing in order to sale it.

2. Creating a parental control app or another user on the iphone Sometimes you share your phone to your kids, a friend or a family member but you don't want them to be able to see your personal info (photos, whatsapp, etc), it would be great if you could actually can put a password or your fingerprint to open apps that might be to much personal or the option to enter to another user without losing the security of the iphone.

Some ideas that could make my life and so I believe other lifes simple.
