Various questions or Findings

Hello Now I have more intensely with the FSE Plugin Pro. I worked on the demo video. However, my questions are getting bigger. 1. I thought FSE was a technoligie to create the website without limitations. So free and not so static to the theme. But that is not so difficult .... it is very complex to understand this technology. 2. There are templates that can be used. But actually I would like to adapt these templates according to my needs before I integrate them into my website. Then I can insert these templates again and again and these prices for my design. 3. I lack a design in which I can have a background image and scroll the text over the background when scrolling or scroll the picture with the text over the standing other content. Like Beom Theme Full Screen Pro. I said that I did it while practicing, but I can't find it anymore. https://vah.ch I missed a slider how I created it in the Theme Full Screen Pro. https://vah.ch My idea is that I can use this plugin and with which all possible websites can build. So I just have to know a plugin and can do everything from it. Or isn't that the idea of FSE? Thank you for your answers. Greetings Heinz
