Rotated geometry shouldn't automatically snap to the grid. You might lose your shape doing that. It's the one thing that would make better floating support welcome in hammer - beyond that you don't have enough building precision to be worth it.

Edit: added automatically and the following disclaimer that despite my comment of floating point support, I'm still probably one of the biggest grid nazis you'll ever find ![]()
