1) See how we have made application tools for the computer version and mobile.
In the PC version on the right at the bottom, normally does not interfere.

And in the mobile version a big enough button at the bottom.
What&aposs the best way to re-register it?

2) Next is the application window itself.
Will you add 3 more fields here to fit the form on one screen of the phone?

3) You also need to issue a window after submitting an application.
