Put a satellite network into orbit between the Mun and Minmus with a great deal of trial and error. Crashed an Ion probe into the Mun testing out the acceleration under time-warp (it's wonderful). Rebuilt a few of my better plane designs from ksp 1 with the lovely procedural wings and paint and flew, enjoying how pretty Kerbin is. Also picked out a number of things that tend to repeatedly cause bugs (at least in my save). Weirdly, a large number of those revolved around the tracking station, which I've just elected to not use for the foreseeable future. Overall I rather enjoyed my time with it today, though it wasn't without hiccups.
