Although I didn't mention it in the pull request, I intended to make this small change, too. It isn't for the planning/context tab, but rather the query "Select Start State" "Select Goal State" sliders - I almost always have my start state the same as the current state and I only want to change the goal state, so this reduces the number of clicks by expanding the Goal State section by default. I believe this is a common use case. It's always bothered me :)
