When I open a lesson I see the tab “resource (1)”. It is great to see with one view that there is a resource. But “1” is shown even if there is no resource.
At the moment we can’t tell if there are Notes are not very easily so this 1 indicates that there are Notes because this is always present in the Resources dropdown whether in fact there are Notes or not. This will have to do for the moment until we add Notes as a part of the lesson itself, like the translations.
