How I can decrease height and move menu to the left side?
Thanks in advance!

Creating some notes for myself, but will post it here, maybe someone will need them ( unfortunately it take a time to read manual, but better with pictures i think

Now I am stuck 
Usualy I create a Page and name it as HOME PAGE and make it as a home page with all plugins, but here manual recommend use POST's as a main page...
How I make all my changes visible in main page without creating PAGE?
