It. Is. Not.
The more companies and people I had been working with, the more I started to see that most of the UI design (or for that matter, displaying information on a UI / document / advertisement) what I thought had become "common sense", hadn't. Most of my colleagues cannot properly position / color a button. Cannot structure a document (headers, tables, bulletpoints) to be easily comprehensible, consumable. Struggle to summarize information in an email.
This 50 UI tips is great! Thanks for this. I will share as a baseline with my team.
