It both makes sense and is counter-intuitive to me at the same time. I see why you did it, and I see why some people would like it that way- however when I hit the back button I'm trying to leave the page, so it feels like I'm being held hostage.

I assure you I'm not trying to hold you hostage. I just thought it would be more useful this way. Guess I'll change it soon, given the feedback I'm receiving.

I'm the original one that complained - and now that I used it as a bookmark reference (instead of being linked from HN) I do see the benefit of the back button. Maybe only have back button navigation if there is no existing history. That way, links to the tool don't hijack existing history items.

With replaceState you can change the URL without adding an entry to the back button list. So you can have a back button that takes you back to HN and a bookmark reference.

It's fine by me and expected behavior. Nice job - very useful.
