It's my first post here! Affinity Designer looks very promising, you have done great work!
There's only couple key features thats' missing:
- rotate canvas tool. This is must have feature if you are going to make affinity perfect for illustrators like me who uses Wacom cintiq and intuos. This feature works perfectly in Corel Painter (and pretty well in Sketchbook pro and PS) but there is no vector drawing software with this feature. I mean there's no way to draw naturally if you can't rotate canvas.
- appearance panel (like in Ai). I use this feature all the time.
