Please add a way to attach a screenshot or any file to an update. If you are referencing something in a comment, it would be helpful to have that file attached to the comment/update, rather than having to put the file in the Documents folder. Additionally, please add a feature where you can remove people from a thread. There are many times you are messaging someone in a thread, and want to keep that conversation relevant to the message right above or the original message, but you don't need all the original people that were tagged in the message. This would significantly decrease irrelevant notifications.
