Is it possible to let the user select the opacity of the non-highlighted text in Focus Mode in a preferences pane? I love Focus Mode, but I wish I could see the unfocused text just a little more clearly without straining. Each user could set how dark or opaque the unfocused text displays.
Is there a similar slider for Focus mode? 
(Linguistic Focus is a different feature.)
Dialog focus on Windows. has a fader as well.
It’s still a different feature.
Sorry, saw Focus and thought that. In Composition Mode there are a number of options for you to play around with. In Windows, go to Options->Appearance->Composition Mode
Thanks, Jestar! However, none of those settings affects the dimmed text in Focus Mode. I’ve searched every setting everywhere, and the setting I’m asking for does not exist anywhere.
