What I am missing the most is, that I can´t open it directly in web browser just with my login without installing anything. In big industry companies is not alowed to install anything, what is not fully authorized by central IT department. I used Wunderlist in my browser (app in chrome was possible to install without any permission), but I can´t use it now in my work browser. Just in my private smartphone. By transferring wunderlist tasks some old and completed tasks are transferred as uncompleted. So, 3 stars for now.
