Puzzle ranking

Hi,
now that there is the "spaced repetition", so I try the same puzzle until I solve it, how is the puzzle rating defined? Same as before?

Also, I am really unhappy of the level selection feature removed.

For example, I've just tried this one:

en.lichess.org/training/61924

I've spent 5 minutes just to be sure it was not a joke or I was not drunk, as the solution was as obvious as a chess captcha. After solving I saw it was a ~1200 puzzle. With the old puzzle engine I would have skipped it because I used to select "high level".

Now, if you can't leave the difficulty switch anymore, could we at least see the ranking of the puzzle before solving it? It seems fair to me.

I think seeing the rating would make you know in advance the difficulty of the puzzle, so you will probably not look it at the same way. In my opinion, it's a nice thing to not be able to see it.

And they said in a blog post some time ago, that they are planning filters/categories for the puzzles, so we will see when this is implemented.
