Understanding UI - Need larger chat font

[Cranky]

My old eyes can't see the tiny text in the chat windows and was hoping there was a UI solution that will let me scale up font size. Alt-Options reveals original and Velious UI and I like the Velious layout but the text is too small on my laptop. I'm no really keen in running installers but can copy a copy a UI folder and edit configs no problem. Suggestions? Ty
