Perhaps you've already tried out this suggestion, I don't know, but I think it would help simplify your current usability of EasyBlog's Blog Title and Blog Description functionality for site owners and admins.
The current "Enable Blog Header" function is what determines whether or not the Blog Description is visible throughout the blog or not. Currently, this function is located in a rather challenging-to-find location, in EasyBlog's tabs, currently under: Layout / Toolbar Tab.
I suggest this layout:
1. Blog title: _________________ ( don't change this, it's fine)
2. Home page only: No | Yes
3. All other pages: No | Yes
4. Blog description: _________________ (don't change this, it's fine)
5. Home page only: No | Yes
6. All other pages: No | Yes
7. Condense all that functionality all on the Layout Tab OR condense all the functionality to the General Worflow Tab. I suggest because this is such an important function, make sure it is on the FIRST tab, by either keeping the General/Workflow as the first tab, or moving the Layout Tab to the first position.
