Other than the screen on the left. It is small window, I want to preview a reforged model in its attack animation and possible change the angle of view but the screen is too small and you cannot preview a model well. Also if stretching the UI it stretches the whole preview in a way nothing is seen well. I try to preview without any background, if the unit could show animation in editor when placed on the map that would also help but maybe the editor cant do that.
