btw: will we be able to customize the News Reader CSS also in the future?

You can customize it right now. The popup tips show the HTML generated by TLB and plugins. I've added the HTML output for News Reader into this topic.

Create your own CSS for this HTML output and add it in TLB Settings->Tips->Appearance.

PS. I'll add something like "Copy Source" into next version of TLB.
