I have found that I need more than this. A document viewer is critical so I can see HTML prototypes, review docs and other output and give feedback contextually inline (through a commenting system). I also need a task lists for my project/ agents so I can see where things are. I created an app like this for myself that is built around an integrated terminal, after I had the epiphany that VS Code (and VIM) were becoming the wrong tool because I am not actually spending time _writing_ the code.
