UI seems improved
I like the ambient light improvement
Here are some bugs which still aren't fixed:
Leaving a ladder by climbing out makes the biome/situation of the landed craft stick to the kerbal.
Holding shift while manually adjusting the position of items in the VAB/SPH allows you to move them ridiculous distances
Situation changes 1 frame after biome does, so you can e.g. get EVA while Flying over Kerbin's Launchpad by doing EVA on the frame right before you land.
Or you can get a Surface Sample from Kerbin's Shores, while you're on the launchpad, by doing the surface sample on the frame before you jump.
If you run a Materials Lab or Goo experiment, and opt to reset the experiment without storing the results, you can still transfer the experiment while it's resetting. This results in the experiment being stored, and the Materials lab resetting, without the need for a scientist.
You're told you have "not enough funds" to launch a craft, while aggressive negotiations is running, if the cost of the craft would exceed your funds BEFORE the discount is applied.
Aggressive negotiations reduces the cost of launching crafts, but does NOT reduce the monetary reward from recovery. So you can launch a craft and then immediately recover it to gain money.
Air-breathing engines (e.g. Wheesley) and their intakes work perfectly fine underwater.
