After having used the new forum for some days now, after a time of adaptation, I have following comments:
1) The sorting of the posts in a thread in reverse order, most recent on top, is a MUST !
When I look at 'New posts' it's anoying to always need to scroll up to the top to display the next 'New post'.
2) Copy the URL of a given post is necessary, at least for me, to reference a given post in an answer and not only the given thread.
3) At the bottom of a tread screen, when answering, I'm missing a 'Preview...' button.
Currently, to preview an answer you need to click on the 'More options...' button.
This is one click more and makes your original answer already as 'edited'.
4) Having a more contrasted separation line between posts would be apreciated.
The current line color is too light or the width too small, the separation is not that evident between the post content and the signature in long posts.
Perhaps I missed some functions.
Of course some comments look like minor 'problems' but even these become boring with time.
Best regards.
