The experiment with Twig, that started last week, is already over. I figured it was way too slow, so I had to find a alternative.The alternative is the good old smarty template engine - a robust and stable product that performs very nicely while still providing a feature set good enough for this project.A couple of templates are already ported - board index, side bar, message index, topic display + a few smaller ones. Hence, this is still just the beginning and there are LOTS of templates in SMF. Compatibility with the old template system is still available though and I do not see any reason for dropping it - both template systems can co-exist without any negative side effect.Consolidated the user menu with the activity stream items. All user-specific menu items are now located at the top right side, providing various quick links to important profile areas plus links to view the activity stream or board notificationsA new way of showing new and/or updated topics has been added. The What's new link will show all new topics from the last X days (where X can be customized by the admin), regardless of the topic's read status. Unread topics will appear like they do in the topic list - a yellow star will indicate a topic with new posts and provide a link to read this topic beginning with the first new post.A couple of styling changes to give the "lightweight" theme a bit more contrast.
