Lost half its use once they got rid of seeing children categories in the widget. I use ToDoist for homework assignments and I used the parent functions for assignments to categorize what class the assignment is for. Without being able to see all my parent/sub folders from the widget it kills most of the use of the app. I went back to an old APK but then I started getting prompts that the app would stop working if I didn't update. I still use it as a grocery list with IFTTT until Keep is fixed.
