Why is "Yo he visto a tu madre esta mañana" more correct than " vi a tu madre esta mañana" for "I saw your mother this morning"? 

Isn´t this a perífrasis?  If so, it would be nice to label it with Perífrasis verbal in the title like the other ones for consistency and for searching for perífrasis  to study.

Hi there, I have (belatedly) discovered Notebooks and am finding these a great way to test myself across different levels and hone in on my weak points. I've added a load of lessons, but it feels like it's focussing very much on the higher level (B2) ones. I want to interleave my practice with my weak points from A2 and B1 too. 

Question: how does it decide which lessons to test from a notebook? Is it random? Or based on your current %? Or something else? 

Also, I'd LOVE a feature where it just quizzes you from your weakest lessons *of those you have already been quizzed on*, across all levels. Basically that's what I'm trying to achieve. 

But this is to do with the nature of this sentence. For other sentences you can replace si with que, for example:

Me encantaría que vinera Carlos.

Me encantaría si viniera Carlos.
