May be not in the exact same condition as yours but I like to keep a separate space for each side project. Suppose, I am working on my portfolio website[1], I switch the view in VS code, Notion, Chrome & terminal. Similarly, for my another side project "system design academy"[2].

Still, struggling to manage multiple projects at the same time. I use linux, couldn't find any tools. Recommendations are appreciated.
