History search

I have 1 doorbell and 3 cameras. I was thinking, on the history part on the app, if you put a search or filter function then you could view a certain day or between certain times of a particular day. Another idea, a button to transfer a video to email as stared ones only stay for 30 days and I wanted to look at the ones I had stared but they are not there anymore, even a different option so you don’t lose the ones you have stared.
