Hi all,
I've just set up an Electrum Cold Storage and it has worked well on my first transfer.  But I do have a few questions:

1. How can I create a QR code from my etherium cold storage, in order to make it easier to send funds to it?
2. Can I create a watching only wallet on the android app?
3. Is there any issue sending funds to my etherium offline wallet, without actually having access to it, or without having a PC with my watching wallet with me?
4. Can I be certain that the receiving key in my offline wallet will not change.  I notice that in my offline wallet, there is an option to view and edit a list of keys.  How can I be sure, when I'm away from my wallet, and can't double check the keys, that I can deposit into it without issues.  Or do I always need to have access to my watching wallet?

Cheers,
