It would be so nice to have more default font styles. I know that you can edit them in your HTML, but that is a tedious template editing process.
Blogger has been listening, and recently, Blogger responded.
The Web has traditionally been pretty limited when it comes to font selection, especially for non-Latin alphabets such as Cyrillic and Greek. But great strides have been made in this arena by our friends on the Google Web Fonts team, and finally there are more choices out there than just Arial and Times New Roman.
You'll find an improvement to the typical Font list, in the Template Designer Advanced wizard - accessed using the "Customize" button, on the "Template" dashboard page.
If you like, you can even add wizards to the Template Designer - and improve colors, fonts, and other settings even more.
