Wunderlist 3 no longer restores a window closed with Cmd+W by adding a new task. Switched to a hopefully temporary workaround of adding a new list then canceling. There are a lot of glitches in Wunderlist when the window is closed so this may change later.
Automated test cleanup was typing #workflowtest in the task input rather than the search box. Wunderlist 3 must respond to the Cmd+F search shortcut asynchronously.
