Amend Quantity in shopping cart glitch

I have just set up a new store.

Have integrated to Paypal and Square - technical setup almost complete - just need to set up the products.

I have a few questions:

1) Client Adjusting Quantity in cart.
If you use the + and - buttons in the cart to adjust the quantity it goes up and down in increments of 2.
So pressing + will change quantity from 1 to 3 etc.
You can set the correct quantity by typing number into field.

2) Privacy policy
Could this be made to work like Terms and Conditions - i.e. to show a link to a popup
Also having trouble adjusting appearance of tickbox and msg in checkout using CSS as no class tags for this individual field

3) Hiding other fields e.g Comments about order
I realise there is no option in config to hide this Comments field.

But a general solution would be to make sure that these control fields had a class or id put in their html tag.

Then in CSS we could easily hide or adjust fields appearance.

I have managed to hide the Add Comments field now with this CSS

textarea#textarea {
display: none;
}

And translating the field label to be empty using translator in eshop config.
