Recently I've written ever more structured posts, and hit the limits of the current forum: it can't handle lists properly, I can't make proper structured lists and lay a sublist or subsection on a list or section.
...and no whatsoever table support whereas it's pretty much a standard in most forums.
Just getting tables would be a major help, as their proper use allows the user to really control how their post looks like and make structured posts with lots of data crammed into it. (You can also cut & past such data into excel for easier use).
