Feature request for Premier Rush

Hi,

Could those lovely developers please add the following feature: 

A 'holding track' that can be muted or unmuted, containing the entire movie file, from which sections can be copied and pasted below into the edited version, without deleting the original in the holding track.  Also 'flags' that can be added to mark pivot points or important moments which would really help when editing a long coversation, for example. Even better, if those flags could then open a little pop up window with a short note/ reference for those important points.

Please please please

🙂
