I'm editing the Wikipedia on a monitor with 3840x2160 pixel resolution. When opening the template dialog in the visual editor, I get a 500x488 pixel dialog centered on the screen. It shows only 2–3 template fields and requires me to scroll up/down all the time.

The template dialog should adapt to the used monitor size (e.g. scale to 80% of the width and height). A good example is the "review your changes" of the "publish changes" dialog.
