Suggested changes are:
1. Make the top section of the history tree "dockable" so that the controls within are easily accessible in larger .IPTs without having to waste time continually scrolling to the top of the list to access.
2. Move the "View" rollout directly below the related "Model States" rollout. These are very often accessed in tandem and when the "Blocks" and/or "Solid Bodies" rollout is expanded, it can separate them by quite a bit. Less of an issue than #1, but would still save time accessing.
Thanks for reading, considering and maybe even voting!
