One key component I find missing from the power 2.0 update is the inclusion of logic interaction. We can manually switch reactors and chamber branches but this would allow for so much more freedom if it could be done via logic giving us a little more freedom in a very restrictive system. You still won't be able to make a ship do everything at once but assuming you already took the time to build the tree out you can switch between systems that are more useful to you at any given moment. We can already do this using the menu but that of course is tedious.
