Even as a command line power user, I still wish it were easier to install dependencies while working in a notebook. If I'm working on a project I don't want to have to switch to my terminal if I can solve the problem in one command from my notebook. With a little careful thought into good UX I don't see why it can't be easy for a beginner at the same time useful to a pro user (and still compatible with any virtual environment).
