Yes, the open arrowhead is much better. (I had no idea Inkscape could be 
extended in this way.)

Good. Looking forward to it!

Please be aware that we may not include the additional figure due to limited 
space. We've inquired with the editor about extra space, in order to include 
more figures, but have yet to hear back. But even if it isn't included in this 
paper, I expect there'll be a later paper more specifically focused on promise 
pipelining anyway. And besides, we can always include it in the unabridged web 
version, along with your colored gradients. ;)
