I think it would be awesome, if you could choose a few more relative difficulties for the puzzzles than ~-600 ~-300 ~0 ~+300 ~+600.
I believe having a few more relative difficulties avaible would be nice, since I've heard on some occasions, that tactic puzzles are most efifcient when you solve ~60-70% of them, when approaching them with full focus. But the ~+0 difficulty will ultimately push you to a 50% solving rate.
So concretely I believe it would be very useful to have a difficulty of around -100 to -150 as an option for puzzles.
