Collaboration with Lucas Chess for training ideas

As a Linux newbie, one free chess program I miss is Lucas Chess at
http://www-lucaschess.rhcloud.com/

There were many fun and interesting training exercises, and wonder if some could be integrated into Lichess, despite being written in a different programming language.

Here is its GitHub: github.com/lukasmonk/lucaschess

I would just like to add that I liked how it could help one's opening repertoire, described here:

Lucas Chess is available for Windows now - downloaded it today and it is awesome - thanks for pointing it out. Just Google Lucas Chess Windows and it's available as free download. I particularly enjoy the range of engines included

Not to mention I've had it working very well with wine.
