Engine component accessible form centre torso
At the moment, you can only change the engine from the overall mech view, from the components list on the left. It would be nice to be able to have the engine tab appear on the components list for the centre torso as well. This is because you have to be in the centre torso view to remove the engine.
It makes more sense to me to be able to add the engine from the same place you remove it. That means you can swap in and out different engines much faster, if you need to tweak engine size. Otherwise there's a lot of going in and out of different views.
