I would rather have no folder limit and have all folders close when pressing the home button, but it's better this way than it was before so I'm not complaining.
 
I like the fact that the folder stays open. In actual use, I don't use every single app all the time, so a lot of folders aren't opened that often, but I have a folder with my social networking sites, and whenever I go to check for updates, I like checking them at the same time, and it is more efficient with the folder staying open.
 
I mean it's a little annoying, nothing OMG unusable. Sometimes it can be helpful. The 12 app limit is way more annoying, especially for games. I have like 50 games I like to bring with me I don't want like 4 folders for games.
