If want to change the default exporting file type, its now easy. Right click the equation and make your choice. Next time you drag-n-drop the equation, the exported equation it will be in a type according to your choice.

Because the equations represent our understanding about some phenomena or law, we can attach a few words about them when we add them in the library. Don't be afraid to make mistakes or to be complete about an equation, because you can always go back to library and edit any bookmarked equation. You can also change its folder location, by dragging it to another folder or selecting another folder from Edit Bookmark dialog.
Anyone makes mistakes, but finding the location of a problem is not always easy. This is where the latex engine parser comes useful, it just shows you where the problem is. If want to see the full latex log, you can go to menu View->Latex Output.
