Please improve the bad UI for external store connections

I'd like to post a few UI improvement requests.

1. When trying to connect my BOOTH store through Add Connection, clicking the "Go to any published product" link opens in the same tab. This makes it impossible to copy the URL and paste it back into the form. It is very inconvenient. Please make the link open in a new tab.

2. During Add Connection, how long do I need to keep the verification URL on the linked site such as BOOTH? Please specify this clearly. Ideally I would like to remove the URL as soon as the connection is verified.

3. During Add Connection, the verification URL must be placed in the first paragraph of the BOOTH product description. Otherwise the check fails. BOOTH supports multiple paragraphs in descriptions. Please allow the URL to be placed in later paragraphs as well, so it can be less visible on the product page.
