Keep the same model when regenerating

If I am working on different things, I might change models for the others.  If I go back in the timeline and hit regenerate, it should reuse the same model for the regeneration!  Instead it uses whatever model is currently selected for new generations.  I shouldn’t have to scroll all the way back down and change the model before I can hit generate again.

Also, I’m with all the others that regenerations should be next to the previous ones.  I would make it like a side-scroller, and offer the chance to open all the generations for the same prompt in its own window so they can all be viewed (and where I can add new generations).
