Thank you for the feedback! :)
I can’t reproduce that. Note that the link in the GitHub README doesn’t lead to the raw PDF but its GitHub page. For the PDF itself use this link.
Maybe in a future version. 
Sure, at the end of the day that’s all it is. The “cool” thing about it is how everything’s integrated with the rest of the template. For example, the score box gets automatically generated depending on the tasks you wrote, sums up all the points and takes bonus tasks into account. If that’s useful to you, you can decide for yourself.
