I spot-checked a few files and left a couple inline questions. They apply to all of the cleanup PRs.

I see that the static imports (for ensemble.xxx) were moved up to the top. Is that deliberate?

apps/samples/Ensemble8/src/app/java/ensemble/samplepage/Description.java line 55:

I see that `ensemble.xxx` is moved after `javafx.xxx`; similarly, elsewhere I see `com.sun.xxx` imports moved after. What's the algorithm your IDE uses to sort imports? sort stuff that starts with "java" first and then everything else alphabetically?

Hmm. This is more than just fixing imports. Were these lines reformatted because they were touching the modified import lines? Anything other than changes to the import statements will require extra time / mental energy to review.
