Assistant cards management

The assistant UI for the app is very nice to have but it becomes a pain to use when things start piling up. The cards become so big that you can barely find anything.

I suggest:
- Changing the cards to a fixed size, have little cards with only the first sentences.
- Be able to select several cards at the same time to bulk delete
- Be able to put a title in important cards so you can keep track of them and save them easily
- A red dot in the top right of the card to indicate a failed task, green for completed and blue for in progress.

Thank you so much for your time and for making such a wonderful app. :)
