Nebula Templates: I will try to get better contrast on the nebula templates, especially for code boxes and the notices boxes.
Reports: This is the moderator/admin bar. Sorry, but this will stay where it's at. For me, I also see user registration alerts here. There is an option to disable the reporting system and send all reports to the staff forum as posts, which I'd consider if there was staff demand for that. However, I think the reporting system is more efficient.
Site Navigation Bar: I really like having the navigation at the top, so it's consistent across the entire site. It's the one element that ties the forum, wiki, and other pages together. I don't plan to get rid of it, although I'd consider appearance changes. I've thought about making the forums that site's actual home page but I don't want to have to put buttons and banners on the forum.
Shift-Enter: I'm sorry, this software doesn't support it and it doesn't seem to be a priority for the devs. On the other hand, you've gained WYSIWYG reply boxes!
Dark Theme: I will see if I can make a dark blue version.
Notices: Most of these can be dismissed (use the X button). I think the only one you can't get rid of is the avatar one. Since we don't have an announcements forum, this is my main way to communicate to the forums users. The notices appear after a certain number of posts, so new users don't see them all at once. I can see conditions for them like post count, usergroups, etc. For example, people in the "site supporters" group don't see the notice asking them to become a site supporter.
