I am enjoying PyCharm's optimizing of Python imports - as well as removing unused imports, following PEP8 gives them a sensible layout and makes them easier to read. Is there any way to get PyCharm to additionally alphabetize them (which would make scanning them faster, for me at least)?
PyCharm does this automatically now by use of Code -> Optimize Imports. It also sorts them into groups per PEP 8.
