Thanks for visiting the Community, @Giffola. I’m here to share some information about customizing your sidebar menu in QuickBooks Online.

The left pane contains the different sections of features in QuickBooks. Personalizing them according to your preferences is currently unavailable.

Additionally, you can change your view by clicking the Switch to Business view from the Gear icon.

I’ve added this link in case you need help navigating within QuickBooks. It includes all the features such as banking, reports and accounting, taxes, etc.

If you need further assistance with customizing QuickBooks, please feel free to let me know. I'd be glad to help you. Have a nice day.
