Use
f.lux to help with the eye strain. It makes the screen yellowish (less blue) and lets you turn down the brightness of the screen. It's a life-changing software.
I just bought a new monitor from Newegg (and didn't pay with bitcoin, BTW), and it has a "night light" feature that turns the blue down. Apparently blue light inhibits melatonin production, which makes it harder to sleep come night time. I just read something about that briefly and will have to look into it more. Either way, it's a great feature that my old monitor didn't have.
That's nothing like the night mode my Android has, though. I really would like to see a true night mode that turns the background black, like Youtube has. And as mentioned, this has been discussed. I'm sure Theymos has read the suggestion, but he doesn't seem to be supporting it.
It's looking fine.
It does look fine, and the forum works great overall, but I think it'd be a nice feature for people who want it.
