Hello.  When adding a new post to the Blog Creative layout, what happens?  More specifically, does it push the other post's masonry blocks down and auto-arrange the different sized masonry blocks?  Can you pick the sized masonry block?  Or is this a manual re-order of the masonry blocks for each post?  Seems as though there are three different sizes, Large Square, Small Square and Full width.  It seems like these sizes may create a bit of an issue if the new post is kept in order of post date.  

Or... do you not pick a size and it simply moves each post down one.  So if post A is a Large Square and is pushed down one, Post A now moves into the Small Square size.  In other words I would not be picking the size, if it's done automatically by the theme.  

Also, I went through the youtube tutorials and did not find an example of the built in gallery as suggested.  I found a slider but that's not considered a gallery.  I can continue to use NextGen but I wanted to sample what you guys offered.

Thank you!
