Sorry, I couldn't find, the last, topic, about the search... (Where is it?)
I think, that it should be multichoice type selections, in the search options: For ex. "Unsolved" and "Untried" could be usefull, to search for together...

Problems search -> Choices type.
Logical Search
What if the 21 strength categories were available in the logical search, as well as the existing 3 broad difficulty classifications? You could then target a narrow difficulty range, working in a slower way and going for a harder group, than when using the time trial.
