Is there a way to have UI3 revert back to the old (<5.4) group layout, where it would manipulate the aspect ratio of cameras to get it to fill the window? I've experimented with all the settings I can find in the UI and nothing seems to get it to behave the way it used to.

Edit: I found a way to do it here: https://blueirissoftware.com/forum/view ... tio#p10454
Very confusing, but it seems to have accomplished the goal
