I've looked at Warp before and seen that it has some potentially useful features for a command line terminal program, like having each command be its own little history window which you can scroll independently and collapse. (I might have imagined/inferred those from the screenshots of it working though). So an alternative implementation does sound interesting, but I would want it just to be a terminal, not with any AI or agent stuff in it. So alas this doesn't appear to be it.
