Improve/expand replay editor

The replay editor currently is very simple but I would like to be able to chain multiple camera shots together to be able to use things like the tripod or free camera modes to join different shots and actually be able to record a whole line without needing to use a follow camera

it'd also be great if you could keyframe things like zoom or focus or camera moves down the line too, maybe with simple lens effects like fisheye distortion or simple filters/exposure/color controls

also please allow some amount of storage to persist between sessions, as well as 'exporting' says it went into my documents but it also went into a deep appdata folder which is much harder for most people to find
