For what it's worth, I stopped training on lichess after they implemented a spaced repetition system for their tactics puzzles. I think it's a shame, it meant that if you wanted to follow any other system at all (even something simple, like doing lots of simple puzzles quickly) you no longer could. There are something like half a dozen different systems you can use for selecting puzzle difficulty/type automatically, so it's kind of disappointing that a single one gets hardcoded in an otherwise very feature-packed site.
