Internet Browser/App Help

[berggreb]

Hey folks, new here

I was hoping someone could help me with a few questions I am having.

So I have 2 questions..

1) How can I hide my search bar in an internet app? I can download whatever app allows for this function.

2) Can I lock a user into the internet app? Basically not allowing them to use anything besides the internet app.

Thanks for any help, have a great rest of your day.

Cheers
Alex
