Hi,
1.2.3. Yes, I would recommend you to do that with such CSS.
It's simple and should do what you want.
On top of that, I would recommend to edit the file "address_view" via the menu Display>Views and add the line:
if(empty($checked)) continue;
before the line:
if($this->config->get('auto_submit_methods',1)&&empty($checked)){
That will allow the system to display only one address.
4. Because when the user has several addresses, it makes sense to first display him the list of his existing addresses so that he can either choose one or create a new one.
But I agree that it could be improved.
We'll do that for new version of HikaShop. You'll have to wait (one or two weeks) as the modification is a bit more involved than just adding one line of code in a view.
5. With the Business edition, you can edit the emails via the menu System->Emails. There you will be able to change the date format on that line:
<?php echo JText::sprintf('DATE_ON_WEBSITE',hikashop_getDate(time(),'%Y-%m-%d %H:%M'),HIKASHOP_LIVE);?>
6. If you edit the email as explained on point 5 you can simply change that line:
<?php echo JText::sprintf('BEST_REGARDS_CUSTOMER',$mail->from_name);?>
to:
<?php echo JText::sprintf('BEST_REGARDS_CUSTOMER','Your lovely shop');?>
