forumlist_body.html and viewforum_body.html don't provide any way to add new columns (like, for example, the number of posts and topics that a forum has) to the lists. Adding a new template event doesn't quite solve the problem because prosilver's CSS doesn't consider the possibility of having more than the default columns.As a new style is being developed, making changes to prosilver right now might not be worth it. It would be great to consider for the next phpBB style the possibility of having new columns added by extension developers by adding new template events and using some kind of technology like Flexbox to avoid hardcoding the column number.
What do you guys think?
