Glyphs: Scale only the arrow length instead of the whole glyph size
From UserVoice.
The glyph filter has the nice property which allows to scale the glyph. However, for all arrow glyphs, a better way of scaling would be to scale only the length of the arrow by a quantity instead of the whole arrow (shaft and tip thickness). This simply gives a much clearer overview if there are regions with big and small arrows in one domain.
