The HTML Page builder looks like a much needed feature! So far it doesn't seem to work though - when I drag an HTML Text block to a column, it won't "stick" - it just floats back to the All Items area. Bug or just not finished?
Thanks Andrey, got it to work but I think it's very subtle - you have to drag across lower left corner of new column or it doesn't work. If there is any way to show where to drop the block it will save you support headaches.
