I have no idea if this is at all feasible, but one thing I would really love would be if, on any board where there are stickied topics, there was some kind of thick line that separated the sticky topics from the non-sticky topics. This is an issue on boards with many sticky topics, like the 2020 board or Forum Community (well, less so on FC now than some months ago). I want to do a quick visual scan of what the most recently commented on topics are, but that is more complicated than necessary when there are a ton of stickied topics in the way. If you had some kind of marker, my eye could just start scanning at that marker.
Thanks for putting forward that proposal. I've wanted to suggest this for a long time, but always forgot it.
Another major flaw in the forum software is the lack of utility of the pagination. You cannot jump from one page to the intended one if the difference between the numbers is too big.
That would be useful. I often know the date of a thread/post, but not a narrow enough search field. I have to hop through a board 5 pages at a time to get to the desired date range.
