The principle of uv as much as I understand is to not tinker with virtual environments. With commands like uv run, uv sync etc you shouldn't have to worry about the virtual env and whether it's activated etc. if you are in a project, it will automatically pick up the right Python version . However if you want to do something not possible through those commands you can still get down to the virtual env. Plus for auto complete in IDEs you generally need to select the venv
I use this vscode extension called "python envy" that changes venv automatically depending on which folder of a monorepo you are in, it's great! Wish vscode had it built-in
