Laracasts: History section

Hi, everyone!

I'm totally newbie here and firstly I want to thank all creators for such a great resourse! And secondly I would like to know a little bit more about Laracasts possibilities:

I'm learning "Laravel Explained" series 6th episode now. The video is about Laracasts History section and all videos there are grouped by some period and it's really comfortable. But in my profile all my videos aren't grouped. Was this functionality removed? Do I have some possibility to group already learnt videos somehow?

Thank you all in advance for help!

@jeffreyway maybe you could help me :)
