Is there a way to gain more screen space by removing warnings? any other tips for more screen space without changing the screen?

I understand the need to remove warnings without changing the screen, idilineklein.

Currently, this option isn't available in QuickBooks Online. I can see that this would be a great feature to have inside the program. I'd recommend sending feedback to our Product Development Team. They'll see your recommendation and consider it for future updates. 

Here's how:

1. Select the Gear icon at the top, then Feedback.
   
2. Enter your comments or product suggestions then select Next.
3. You'll be provided a list of suggested Help articles related to your comment. You can read through them or select Skip and send a message.
4. From the drop-down, choose the appropriate category, then select Send a message.
