Other questions

I can see that being able to print an invoice without a password is convenient and saves time, SuperStar. Let me give you a few details so you'll be guided on what you're supposed to do.

In QuickBooks Online (QBO), the system only requires you to enter a password when you open the actual transaction under the closed dates. As mentioned by my colleague @MirriamM, you can directly click the Print button in the Action column on the Invoices page and this doesn't ask you for a password. 

Secondly, for the customer or vendor detail page, you can click the three horizontal lines on the upper part of the search bar for the columns to be adjusted. I've added a screenshot for a visual guide:

After that, this will now show in this format:

Next,  you'll only have to click the Switch to classic view option for the report to revert to the old style. 
 

Furthermore, learn what's in the new layout with estimates and invoices. I've added this article for details: See What's New with Estimates and Invoices in QuickBooks Online.
