Hi Kamil Veselý,
Thanks for your reply. I’m happy to see, that you found our courses very interesting so far 
In an earlier post, I mentioned, that we'll announce some new openSAP courses soon. One of these will focus on SAP’s UX strategy and another one will provide an Introduction to SAP Fiori UX. Registration will start end of next week.
Hope this is what you are looking for.
Cheers,
Clemens
