While I feel for you not feeling able to publish, is it really that sad that we like good icons? Isn’t one of the important things about the platform that we have high ui demands?
I agree with you, I decided to keep it simple (may be too simple lol) so we could ship as fast as possible but I will work on that in the future, thank you for your feedback!
I'd argue that UI is different from prettiness of icon. The skill of drawing and the skill of understanding how to make an application easy to use are different.
While true, this icon has some obvious flaws that could have been fixed with "draw polygon; sides: 3" in any free or premium editor.
We are affected by aesthetics. Humans like things that look good, use those objects more, find the objects easier to use, has a lower cognitive load on us, etc. Atleast that is the results of the cognitive studies I know of (like those 1990s studies from Hitatchi).
