If you were a teacher, what would be your main question/concern about Improveo?

If I were a teacher my main concern would be time - how long will it take for me to learn how to use this platform & how long will it take for my students? If I have questions or issues with the platform, how long before I get a reply from support? There are only so many hours in class in the semester and I want to make sure it is being well spent.
