You can set the Theme62 template directly in Blogger Layout as in the following settings :
- Menu Navigation
- Plugin - Insert to Post
- Plugin - Watermark
- Plugin - Lightbox
- Plugin - Table of Content
- Plugin - Split Post
- Plugin - Live Search
- Plugin - Disable Copy/Paste
- Plugin - Shortlink
- Plugin - Safelink
- Plugin - Single Page Application
But in some widgets it is quite difficult to edit manually like the Menu Navigation widget.
That's why Theme62 created a Widget Generator tool to make the code as easy as using Dashboard Template.
