More fine-grained difficulty level selection of the problems would be great - I'd love to select problems from 8k to 2k only, so I don't get any trivial or impossible ones, only those I can do, but make me think a bit.

Difficulty levels
I second this with gusto.
Please, please, please!
It would allow one to go through, say, 50 problems of life & death, as if one was reading a go problem book, which would be cool++. (The "next in set" feature is brilliant.) Choosing random order with "easy" difficulty creates a much too varied (for a 15 kyu, every other problem might turn out to be either trivial or incredibly hard...).
Better yet would be the ability to select upper and lower range in the vein of the time trial difficulty levels; e.g. "I want 50 random tesuji problems of approximate difficulty 10 to 5 kyu inclusive".
It can't be that hard, can it? .. prob.solved / prob.tried AS level .. WHERE level >= %1 AND level < %2.. Nevermind me...
Edit: This forum is weird. After the search, clicking on the topic I found, it only showed me the first post, so I didn't see the reply from Adam -- so sorry if I seem a bit pushy when it had already registered on your radar.
