More practices!

Lichess has 125272 training problems, which I wouldn't call "very few."* That being said, if you want more, I'd recommend ChessTempo: https://chesstempo.com/chess-tactics/.

*I think only about half of them are still in use, older puzzles were generated in a different way and they no longer show up.

This actually reminds me of the fact that i have not finished practice. Yes most of those are fantastic and OP is right we need more of those.

yeah it is a great section, but I think adding the studies was a sign that they are not going to develop practice anymore. It was like: enough spoon feeding, here is a great tool to learn anything you want, it's time to create your own content

#1 “We but mirror the world. All the tendencies present in the outer world are to be found in the world of our body. If we could change ourselves, the tendencies in the world would also change. As a man changes his own nature, so does the attitude of the world change towards him. This is the divine mystery supreme. A wonderful thing it is and the source of our happiness. We need not wait to see what others do.” – Mahatma Gandhi

(In other words, I like the idea but don't have time to do it.)

@kapibarr you don't have to restrict yoursef to official lichess stuff. There are countless very good content created by lichess users.
For example these studies was created by https://lichess.org/@/thijscom

@kapibarr
It would be helpful if you were a little bit more precise.
Which kind of things do you want to practice more ?
Could you make a short list ?

@kapibarr I understand you, but lichess Practice materials are exactly the same interactive studies what you and any user can create itself. Lichess developers are not GM level chess trainers who dedicated to produce free high level interactive studies in his free time :)
But as I mentioned before you can find several good one here https://lichess.org/study/all/popular
For example
