Hi @shanticfm,

I hope you are well today and thank you for your questions.

Hello, I’m using the project feature as our gallery and would like to remove the title of the project.

You can achieve it by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

body.page-id-4472 .sh-titlebar .titlebar-title h1 {
    display: none;
}

I would also like to add the option that when you select the image to enlarge it, that you can select the next or previous image without exiting that lightbox.

You have to develop custom code to achieve this.

Developing custom code for custom functionality is beyond the scope of support that we provide here. Please see https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support

If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5

Best regards,
Shufflehound team
