Hi,
1. Yes, you can change it here: https://i.imgur.com/MY37SRo.png
2. Sort of, but not exactly. You could enable the auto-populate feature, which will fill the elementor container with initial default search results.
3. I don’t think this is actually possible without custom coding. The initial Elementor container could be hidden via adding a CSS class name, then removing it once the initial search is finished, but that requires coding for sure.
4. Sure: https://i.imgur.com/y5sotmO.png
