uses of the tense addition would be useful

Hola Mona

In lessons that are explaining and testing conjugations we don't tend to give too much detail about uses because the focus there is on formation of the tense. We normally connect them to other lessons that explain in more detail a specific use of that tense. Here's a separate lesson talking about the present continuous as opposed to the present tense that will help.
