Don't like it. The thick giant buttons remind me when Microsoft switched from Win95 to XP, with those clunky buttons that used up too much screen space.
But that's not what bothers me. In the old format, the 'New Posts' screen was a table of 'Thread Subject', 'Number of Replies', 'Last Post', 'Views', and 'Forum', and it was really easy to scan for the posts I wanted to read. Now the info is not in table form, making quick scanning harder.
No, sir, I do not like it.
