I think this is overkill, since it's not essential functionality, it just makes reading easier.

That's true, the contrast it just too much and tires the eye. Where I live it's extreme contrast it' very bright before and after noon from all the snow reflections, then it turns dark very soon. > > ∙ reading PDFs in a dark environment.

Thanks for the tip, I've never heard of that tool. Actually I didn't know it's a common problem, I thought my eyes are just more sensitive. I will try if I can get comfortable with redshift, it sounds very promising. Marco -- To unsubscribe, send mail to [email protected].
