Question about lists of lists

Just wondering what's up with the format of lists of lists lately. It used to be that the lists contained within were placed side by side in pairs when "Collage view"/"Default" was chosen, but now they're stacked one on top of another. Also I just went to try to add a note to a list I added today and couldn't even find the "Add note" button to do so (Lists I'm following is my list & I tried to add a note for the list called "TheCount's song of a week"). I know the "Add note" button has always been hidden anyway on Lists of lists (odd choice by the way), but with the formatting change I have no idea where it's at now (I am, however, able to find the "Edit note" button on the other entries in the section that already have notes from before the changes).

So basically I'm wondering if the formatting is permanent or temporary, as well as whether the Add note button issue is just a bug or what. Personally I'd like to see it go back to the way it was before, as the side by side display was more visually appealing/interesting.

Sweet, back to normal. If my post in any way influenced the change I'm pleased. And if not that's cool too. Just glad that that list looks as it should & I can add notes again. Thanks! :)
