Answer 1

As Kevhendar has mentioned above, you can of course create a native app using Sencha Touch. Here are my understanding below:

Question #1:

YES, Sencha Touch does allow you to create apps that run like native applications (full screen apps as you say) on your mobile devices. One of the powerful features is that you can develop native applications (though technically 'native' refers to app that are created using core technologies) as well as mobile web apps. So, the answer to your question is YES, you can hide the status bar by building your app with native packaging tool (link mentioned by Kevhender).

Question #2:

YES, you can create app-like apps using Sencha Touch. A part of answer can be found from above.

Question #3:

My understanding is that you do not want the user to exit the application just by tapping the exit button or close button just like we do on a website. If that's the case, the answer is YES. When you create a native app using Sencha Touch, you obviously do not have the option for an user to have a close button or something like that.

Question #4:

This is not clear. However, if you want to run your application on startup. you need make some permission in your manifest file (Which I think it has nothing to do with Sencha Touch).

I hope this helps you by some manner.
