Input speed: at the moment, the keyboard might as well not exist for the game; the only mapped key seems to be ESC - and even it is not fully functional, because phone/inv modals do not respond to it. If we dedicate ourselves to perform the available several dozens of actions hundreds of times
over and over, most of us would benefit from proper keybindings - for instance, 1 through 9 for the rooms, QWERTY for the action list inside a room, 1-9 keys for the topic selector bars, food/sleep list, etc. As a bonus, this would keep one hand free
Even the 'Continue' buttons in the oft-repeated actions with multiple pages must currently be clicked manually!

UI locality: in absence of keyboard navigation, the player's eyes - and sometimes mouse, - must jump all across the screen, causing fatigue and disorientation. The phone/inv buttons: bottom left corner, action buttons: bottom-right corner, stats: top, convo output: top-left, NPC convo output: top-right. It's even worse for QHD/4K resolutions. For instance, it would be possible to aggregate most of the UI elements in one location: room buttons + action buttons (as Big Brother has action buttons
right next to room buttons), and stats could be drawn in the near-left, FPS style. The UX locality laws mandate the top part of the screen, I believe.
