Post timeline tracker
Just trying to understand what exactly you're asking for here:
At least in infinite scroll mode, we already have the post position overlay. It shows up in the header bar for desktops and at the bottom of the screen on mobile devices. The difference with Discourse in that case is that we don't have datetime information and the position in different.
So are you asking that we add post datetime information, or that we add the post position overlay even when in pagination (not infinite scroll) mode?
Our forum is in paginated form, so I was not aware of this function... I was writing for paginated design so everyone can use it, but apparently infinite scroll design is already using it...
So, in this case my question will be about paginated forum...
There are redundancy and lack of buttons..
two << (up) or
one < (up)
two >> (down) or
one > (down)
two arrows takes you either to the first or last post of the topic... one arrow takes you previous or next posts...
However there are already pagination, so you can go to first or last page with pagination anyway... with these settings there are no way you can go to the top of the page, or to the bottom of the page (I meant first post of the page not the topic or last post of the page not the topic), you have to scroll to the top or to the bottom...
I think it will be more useful if two arrows take you to the top of bottom of the page rather than topic... If people wants to go to the first page or last page, they can do it using pagination anyway...
