[Bug] Model selection affects all tabs instead of being tab-specific

Bug Description
When switching models in one tab the model is switched in all tabs. This is not good design! Idk if its always pulling from a config file or something but its one of MANY bugs that was introduced recently. Honestly,,, this whole interface feels like a brick in a washing machine at this point.
