RenderCue

important note, it doesnt use VRAM

Very usefull render queuer! And the great news is it works with linked scenes! So this way you can queue renders from multiple file scenes without having to create an enormous blend file.

The expected news is that it doesn't support ffmpeg output (or at least it's not documented how it does - or doesn't). The bad news is that at the moment it doesn't warn you about it if you forget your settings to ffmpeg (it's even allowed in the override settings, which doesn't make sense, unless there's a way to point to ffmpeg executable too?) and silently fails to render.
