I was really hoping for a proper Tag Management and got kind of disappointed. There's nothing that speaks against #hashtags in the reminder's notes … but it could be displayed much better. For example, a dedicated "Tags" section in the reminder details. And, of course, I want auto-complete once I type the hashtag #.
This would really improve GoodTask over the Reminders App.
The second topic is the handling of subtasks. Apple's original reminders App already knows Subtasks. Why isn't this handled the same way in Goodtask? Would help on switching apps.
