I love these kind of spoilers, and hope to see more of them 
Can we get an update (perhaps in the form of a dev blog) on the status of Photon UI development? Can the team tell us any specific player-feedback ‘pain points’ that are being considered for changes?
• Will basic UI conventions like minimize/close be exposed on ALL windows and sub-window dialog pop-ups?
• Will it become easier to distinguish “streamlined” elements, like scroll bars and line elements that separate types of information or groups of controls? (Dark color themes make controls and separation elements that have been ‘streamlined’ even more critical to feature discoverability / usability: clicking in the right place, the first time.)
