ability to delay, but not block, websites
It would be nice if I was able to "delay" the loading of certain websites by say 30 seconds or a user-entered amount. (see the title/hover text of https://xkcd.com/862/) This feature may not be useful as a porn filter, but it would still be useful in cutting down on compulsively checking innocent websites and/or preventing "binges." For me, the big problem sites are YouTube (videos allowed) and Reddit (without vids or pics), which have lots of good information, and are mostly safe from porn (when setup as described), but can also suck me in for hours on end.
(OP here) I actually found a good solution to this, if anyone wants to do a similar thing: check out the Chrome plugin "Leechblock." You can delay by url and password-lock it too (and put the password in a Pluckeye Lockbox) (get the plug in and play around with it to see what I'm talking about)
