I'm a new streamer, and I'm really struggling to get the RTST Streaming Overlay working correctly.

When trying to set up the streaming overlay, it always wants to default to 1920x1080 - a resolution I simply can't use due to bad eyesight (and a monitor that doesn't support it). The "edit" image renders adjusting the HUD completely useless as it pushes the stats and killboard over to the right - outside of my screen.

Is there currently, or will there be in the future, any way to scale everything down from 1920x1080 to other resolutions? Or am I just being utterly useless and missing something obvious?
