I made a video on how to save a page as a template in Elementor. I had this problem around the time I started using Elementor Pro. In the case where you have similar pages, Elementor Them Builder handless most of it but you still have the content left to replicate. I used to copy each section and paste it to the new page one after the other until I stumbled on this. It’s helped me a lot since then and even now, I’m using it on my website.
A very good example is where you have a bunch of pages for services. They’d have similar page structures so you’d want a copy and paste situation where you only need to change the pictures and texts.
This is also a practice video for a programming youtube channel I’ll be starting soon.
