Those icons are pretty nice.
I was thinking that one thing I'll really miss about Adobe's products is that, like Apple, they seem to put a lot of emphasis on user experience, not just features/capabilities. While I think Affinity Designer has some really promising looking features, I think a more consistent experience and modern/flatter brand would go a long way. Though i'm pretty sure it is obviously not the most pressing of issues for the Affinity team. I think Adobe has had years of fine-tuning under their belts, and they obviously have a large claim on the market, so they can afford to do more in these areas.
One thing I've noticed so far by watching videos and looking at screenshots of Affinity Designer is that a simpler, more refined UI might complement the amount of features better (it seems that the top workspace panel when in a certain mode seems kind of bloated).
I think Affinity's community base is seemingly small in comparison with Adobe, so there's less gridlock maybe. One of the benefits of this circumstance is that it may allow a more organic growth, and I think where branding and user interface/experience is concerned, there might hopefully be some community interaction in how the Affinity brand/aesthetic develops.
I just cancelled my Illustrator CC subscription today, and i'm looking forward to getting on board with Affinity.
