Currently, I have working html page. Pages are in max 4 columns layout and unlimited rows now. If there is not enough space for 4 pages in row, layout will automatically switch to 3 columns.
What is not implemented yet?
But this feature will surely come to 1.1.0 release :-)
I think the design is sufficient enough to not to change very much in release. Just look by yourself!
