I've taken a liking to pixel art lately, & zooming more with an option to turn of anti-aliasing would help with such drawings. I'm not sure these would help much though because it seems Black Ink blurs everything on screen a bit every so often.
I'd also like to see a select tool with an accompanying set of resize & warp tools. I'm not sure if resize & that kind of thing is what this program is intended for though.
Anyway, good luck with this program guys!
