I’ve been doing a lot of mockups including link-node/network charts and the arrows on lines are essentially useless. They’re far too large - so the ability to adjust scale is crucial. The available arrow heads could also be expanded - we’re desperate for a non-rounded line arrowhead!.
We’ve had some updates to strokes lately which has been good to see but nothing for the caps.
I’d be happy with the scale option but even happier if I could specify a width in px. Adjusting the size of arrowheads in Illustrator is so clumsy, 50% of what?
