Yes, this will be very helpful. Then we don't need to use third party plugin like popup maker. A Popup is useful especially for Call to Action.

I suggest flatsome must test other builders like elementor, beaver or divi and drop the ux builder altogether for its theme. UX Builder is great in terms of productivity but not as advanced and full featured as other popular builders like elementor pro which natively support pop ups.

Yes would be great to see built in on Flatsome

Agree! The7 theme brings Convert Plus on its core. Would be great to have that outstanding popup plugin!

You can already do this in flatsome. Simply paste the below flatsome light box shortcode in the advanced footer section (or a page), then call on it with the # ID you choose.

[lightbox id="myid" width="600px" padding="20px"]Add lightbox content here...[/lightbox]

This could be great, since a lot of the features needed are already available in the theme. The standard timed popup is not recommended by Google but a good idea would be sticky buttons like the ones you can see here at your right: http://flatsome3.uxthemes.com/demos/business-demos/explore/. They open a full screen overlay. They would be awesome for lead forms, support, contact, etc. The possibilities are endless and they are already done for the demo site :)
