Fonts on macOS are too small

See this request from X:

I think it makes sense to change caption to body for just the network requests. Potentially, we can make this optional by providing a small and normal size selection option in the header on the far right of the tabs.

Thanks for the report; it was absolutely the case. I increased fonts in mulple places on macOS. I'll continue making small tweaks as I work on the new interations.
