Two fixes for things that went wrong quietly.
- Window Fan (and Deck, the switchers, Undo) could now and then find no
windows at all: for one moment macOS answers "no such app" for every
running app, and Hammerdeck took that at its word. Fan showed a brief
"No windows to fan" and did nothing. Windows are now listed whatever
that lookup says, and every time Fan or Deck declines to start, the
daily log says why. - Undo after a Window Grid placement puts the window back where it was
before Grid. It used to stop at the first cell you pressed. - When a window refuses to move back, Undo says so -- "Couldn't move 1
window back -- press again to retry" -- and pressing again retries.
It used to report "Nothing to undo" and lose the step.
