Hi there, nonethanks.

Thank you for visiting the QuickBooks Community again, nonethanks. Let me discuss different details on how viewing all the features in QuickBooks Online works. Then, I'll ensure you'll be able to view all the tools in the program after following the steps below.

There are two ways to display your account in QuickBooks Online, as Business and accountant view. Your default view is based on what you tell us when you first set up QuickBooks. With this, if you're referring to seeing the sidebar menus that have Dashboard, Banking, and Sales, I suggest making sure that your QBO is set to Accountant view. 

Here's how:

1. Click the Gear icon ⚙.
2. Go to the Profile section.
3. Choose Switch to Accountant view.

I added a screenshot below for visual reference.

However, if you mean viewing all of the tools on the left panel and you can't see them, it's possible that the Hamburger icon was clicked to hide those menus. I recommend selecting the said option to see all of the tools so you can begin re-learning and navigating.

Lastly, I'm adding this article to further guide you in effectively managing your business using QBO: Help guide for QuickBooks Online. It contains topics about advanced accounting, banking, and payments to name a few.

Let me know if there's anything else you need help with all the features in QBO by clicking the Reply button below. I'm always here to help you, nonethanks. Take care and keep safe!
