Feature request: Format arrows

Disclosure: Spoiled by Visio (but prefer Scapple for relatively simple diagrams). I’d like to see some options for formatting arrows (line weight, arrowhead shape, color). Use case: I incorporate Scapple diagrams exported as images in Powerpoint presentations. When creating the diagrams, I can (a) use large fonts that will be very crisp on screen but with tiny arrows or (b) use small fonts and scale the image up, making larger arrows, but sacrificing crispness on both text and arrows. A small annoyance, but an annoyance nonetheless. Thanks.
