Thank you for your comment @ocanada!
I am glad we already have some of your wants on our list already!
Yes, mostly we have heard positive comments about the colors. However, depending also on the quality of your screen, brightness and contrast, this could be a little bit off.
This could be a potential feature in the future though (eg. also steemnow offers to switch to light/dark theme). I like the idea! Not quite sure if we will deploy this in the near future - but definitely something to keep in mind for the long run. Thanks!
