Great! thanks for the link.
I think it would be a good idea the hack to become a plugin later.
Thanks!

Content Drip add-on for LearnPress is related to what i am asking for? Btw, I am thinking of using your theme; is this plugin included in the theme or do i have to buy it separately?
Anyway, unless you catch me, i am thinking of solving this with a hack: enabling the button “complete this lesson” after 30 sec, smt like firefox extension installation button

To make it more clear, can i set time limitation for a lesson to be set as completed?
