Hi@pureivan

It seems that you are accustomed to the old style QuickBuild. So far, there is no option to make the new GUI more compact like before except you write some custom CSS in Administration page by yourself. If you only want configuration tree be more compact, you may add below lines to your Css Customization in Administration:

table.treetable {
    --table-td-padding-y: 3px;
    --table-th-padding-y: 3px;
    --table-font-size: 12px;
}

or you may file a ticket in our issue tracker below:

That's exactly the result I was looking for, thank you!
