Add description to group/folder
Adding descriptions to folders (now groups) would be useful when you're using a group as a category for tasks. This might be catered for with parent tasks.
When I'm creating a bunch of tasks (say for a newsletter) and there are three people working on it, I want to be able to explain what the group of tasks is - not just the tasks themselves.
We do have plans to release project descriptions in future updates, but for the time being we’re not opening this to groups.
