Thanks very much for the screen snap, @Richardus.Raymaker . It’s good to see that the font sizing is good for you with Windows at 125% scale, now. To make it more legible, I changed the font to one with thicker strokes, increased its size a fraction, and hardened up the contrast.
Regarding font weights - normal, semi-bold, bold - I think I’ll leave them how they are, at least for now. If everything’s bold, then to call attention to things you need to make those things even bolder, or bigger, or … and can end up with the UI shouting at you. I understand why fonts are bolder in HiFi’s entities editor: to make text more visible in HMDs. My edit’s emphasis is on the desktop use case, with greater information density, and rather than comparing with HiFi’s editor fonts should be compared with other desktop applications.
It also comes down to personal preference and what you’re used to. I may have over-hardened the contrast; I may back it off a little.
