I Agree - this would be brilliant - slack is brilliant for reducing the amount of email - and this kind of notification perfectly suits slack. Please do this asap!
Just had the same problem - double click on the top folder (i.e the account name) and the folders all disappear and appear again.
Thanks Nathan - we're using Google sheets manually at the moment - so that might be the first port of call.
We need this too please. Asap. We use tasks as user stories in an agile workflow. Subtasks are development tasks. It's vital to be able to easily see the total time on a user story built up from it...
Yup - thanks Stephen - all sorted.
