Portrait Layout is straight forward, but can be wanting in certain scenarios such as when the subject of one of the two panels is moving between the left and right sides of the screen (say Mario isn't always centered for instance) or when certain context is needed from another region of the screen (say health or ammo in different corners from the streamer). When I encounter such scenarios the Twitch editor is not good enough and I need to take it to an external editor to get the job done.

I would suggest following features.

1. Allow moving the Panels e.g. Pan and Scan style either instantly or over time so as to better track the action when needed.

2. Allow adding a 3rd tracked area either as a third division vertically or overlaid over the existing two. This would be handy for, say, putting a health indicator onto the screen for clips where how much damage is taken stupidly is key.

Also, not really related to Portrait Layout, but allowing there to be cuts in a clip would allow for more flexibility in what fits in a one minute clip - sometimes a moment nearly fits but you'd have to edit out something externally to make it fit into a YouTube Short.
