title: How to disable the grey background colour on iterm2 desactived tab split?
body: <p>In iterm2, by default setting, only the current using tab split will have the normal black background colour, meanwhile all the other tab splits will be covered by a fog-like grey background colour.</p>
  
  <p>I know this may be designed to improving concentration. The problem is, sometimes I really need to view two splits at the same time. And this fog-like grey background colour has increased the difficulty of reading.</p>
  
  <p>Is there some way to disable this feature?</p>
