Hi, 

Please check my answers below: 

I downloaded a plugin to remove the page title from my home page. Is there a way to hide page titles that is already built into Artemis that I don't know about? I'd rather use Artemis functionality rather than keep another plugin. Any help appreciated!

Yes, it is quite easy. Please go to Appearance - Customize - Additional CSS and add the code below: 

.single_post_title h1, .heading_area_title h1 {
display: none; 
}

Please let me know how it works.

Also - I upgraded to Elementor Pro so I could have more templates and all the building capabilities. For headers, it pulls from the wordpress logo upload. However, Artemis bypasses that by putting the logo upload in the Artmeis customization area and removing it from wordpress customizer. Elementor does not know to look in Artemis area so it can't find the logo. I can't upload the logo into wordpress because Artemis removed it. This means I can't use any of the Elementor headers available in Builder.

Can you please offer some screenshots for better understanding? No worries, I will help you with this, but I need to understand the issue.

What do you mean by Artemis customization and what is the difference between this and WordPress Customizer because Artemis has its own entries in WordPress customizer. The logo itself is set in Artemis settings.
