As a math instructor I really need this type of feature as well. My cohorts use Notability on iOS, but I'm an android guy. I need either triangles (right angle) added to the shape feature, or PREFERABLY shape recognition. I just purchased the upgraded version of squid with the hope's those features would be there, oops. I'll likely have to try another app to find this, unfortunate as squid seems pretty good.
