About the default value of the Font dropdown. This tool is not designed to has a default value neither to arrange by some specific logic the set options. Using a default value on this tool would be a faulty behavior, because the user that is using the editor should choose what font to use and additionally this tool will show what font is already set to the selected text (the place where the cursor is set). Setting a default value would lead the user to confusion what is exactly the used font. For example, the set font to the body is Arial, but programmatically the tool is set to Times New Roman, each time the user selects a text, the tool will show incorrect value.
About setting the same as the default value explicitly is already implemented in the 2014.1.225 version. I assume that you are using an older version and to resolve I suggest upgrading your Telerik controls suite.
