The ability to build things during a flight has been a feature I've been wanting for years. This has opened up so many different mission profiles it's super cool. As an example, I recently put up a science base on Minmus. It's been a long time since I'd played, so I had forgotten the finer points of science processing. I didn't have enough battery power. Before this update, this would have been a failed mission. However, with 1.11, I was able to send up an engineer with a few batteries and extra solar panels in stow. I was able to fix up my mistake, and now it looks kinda makeshift too, which is pretty cool. Great update fellas!
