Is there any option to export finished tasks as pdf,doc,etc.. in a given period of time?
Not directly, but there's a workaround. You can click on the Karma score at the top, then choose "View All Completed", filter the list as you like and then click on the gear icon and choose "Print current page". If you have a "Print to PDF" plugin in your browser, you'll be able to get a PDF file showing these tasks.
And how can I print notes inside some tasks?
Just click on the gear in the upper right corner and select "Print current page". Just click "OK" if asked to include notes in your printouts.
I have tried "Print current page" but after to click in "OK" there is not asked to include note. I´ve seen this question in open tasks. So I continue without a way to print notes of finished tasks
Hello Luiz Antonio,
Indeed, it's unfortunately not possible to print notes from completed tasks, but we'll consider adding this option in future updates.
