description properties

Hello,
I installed your plugin yesterday, and would like to go pro version,
As I am using the gallery /content pop-up, I’d like to know if it is possible to start new paragraphs in the description box with the pro version? And in a larger purpose,to change the fonts, etc in the description box.
It seems that it is impossible to do that in the free version,
thanks!
