Attachment to mail and Weekly events in cakendar

Please Apple stop making IOS look beautiful and start giving us functional and practical apps. Why can we still not add attachments from within an email? And please please if I add a new event and select repeat Weekly why does it STIL NOT GIVE ME DAYS OF THE WEEK TO REPEAT? I am a personal trainer and clients train same time on dif days. Now I have to create dif events for each session.
