There are some StackExchange pages, as well as blogs, which have LaTeX integration, e.g. https://mathematica.stackexchange.com/. On these pages one can simply write math LaTeX code using the $ delimiters. Is there any EMail editor/plug-in for Ubuntu which translates LaTeX input to pictures, or keeps it as LaTeX, and parses it in a nice way?
If not, is anybody aware of a tool, in which one can input LaTeX code, and the output is an image? Drag&Drop is appreciated.
Mac's Preview can be used to rearange pages in a PDF document by simply drag-and-dropping the pages around in the side panel. Is there any equivalent tool for Ubuntu? I have noticed, that the Document Viewer, which comes with Ubuntu, also has this nice side panel. However, it cannot be used to manipulate a PDF document. If there is no drag-and-drop solution, what is the easiest way to rearrange pages in a PDF document?
