Trello is beautiful task manager. But I get some difficult of task exporting to different formats such as pdf or plain text.
Now there are two variants of export: print and json.
You find them: click "show menu" (hot key: w), find "more -> Print and Export" and choose format:
You can save your tasks in pdf, chosen pdf format in print variant. It's not beautiful view. We get big font.
Other variant - json format, but it's not for usual users. It's for programmers. They extract data and present them in friendly view.
Fortunately, I am programmer...
