Here's the first release it's small but it's something people asked for.
The "View New Content" button at top right shows either:
1) Show me all content that I have not read
2) Show me all new content since my last visit
Based on your settings ( http://www.neocodex....e&module=usercp ). Now if you want to see what you are used to seeing in IPB 2 you want "Active Content". To access this click and hold on the "View New Content" it will toggle to "View Active Content". You can toggle back and forth between the two. It will stay the mode you picked from page to page. However not from computer to computer. It uses cookies.
All three modes are different. Test them out to figure it out.
The only issue with it is that you can't right click and say open in new window. This I'll look into promise. How much of an issue is this though?
