A lot of this seems similar to what plan 9's acme editor provides. You can run shell commands anywhere and their output is written to a new window. You can also run an interactive shell in a window and edit the text directly. I have been using this as my main dev environment for a while now and I just hate when I need an application that tries to use fancy terminal features with no fallback.
