I used to use the top navigation to get between iMore and all the sister sites, as iMore is the shortest to type, it was the first, so when AC switched to this layout, it didn't bug me *TOO* much, as that became the last on my cycle. Now, and I know it's first world problems, but I have to type out each site, or scroll all the way to the bottom to select from there. I also have to load the entire forum pages just to see what the top posts are. I used to be able to see a preview of each.
Not to mention the site chokes with FF up to date on an i7 with 8gig RAM. I do keep a bunch of tabs open, but wasn't an issue until now tbh.
I normally don't get why people want to "downgrade" things but in this case, I am really looking for GreaseMonkey scripts to change back to the classic layout.
