TreeView Header text not centered

How can I control the text/ formatting of the header, it’s huge and far too big for my application. I tried changing the Headerheight, but the text is not centered.
Would also like to be able to add icons to the header

Please check the related sample: http://docs.webix.com/samples/15_datatable/12_header_footer/12_lineheight.html

Here all needed properties are specified in the configuration of the header:

{ id:"title",	header:{
	text:"A multiline header ... really matter?",
	height:120, 	// height of the one header row
	css:"multiline"	// line-height, etc.
},

You can apply the needed formatting with css property. Any content (icons as well) can be added as html:

Also, you can use headerRowHeight (total header height) and headerRowLineHeight (global line-height for header) properties.

As usual you guys deliver the goods. Looking forward to the weekend to check this out.
