I would like to use "highlight_line": true, but I’ve found that when I switch from Sublime Text 3 to another application and switch back, it makes me have a hard time telling which group has keyboard focus. Even though I have to look for the blinking caret in both cases, the highlighted lines in unfocused groups end up distracting me. Even though the highlighted line has a different background color in the focused group than in unfocused groups, the difference is too subtle to be effective for me. (I don’t even see why I would care what the current line is in an unfocused buffer.)
Is there any way to highlight the current line only in the focused group? Or alternatively, is there any way to control how the highlighted line appears in unfocused groups? (I’ve looked at Monokai.tmTheme, but I couldn’t see any obvious way to control the line highlight color independently for focused vs. unfocused groups.)
