The solver message lacks of visibility, it's not very clear to quickly determine if the game can be won or not, since the message has the same black color, and just varies of few words. Reproducible: Always Steps to Reproduce: 1. Just play. Actual Results: The solver message is black in any case, it demands "some efforts" to know if it's possible to win. Expected Results: The solver message should be quickly understood. What about using different colors to distinguish both states (possible/impossible) ?
the solver should not get in your way of solving and just be a aid.
Typically, when I'm playing on Klondike, I'm often watching the solver message in order to know If I can continue my game. So I quickly need to determine it, and a message color should improve it. Thus, the solver has a (big) impact on my game, since it's not just an occasional and discreet helper. You consider that it shouldn't, no problem, I understand your point of view, you've not designer the solver for that.
I do know what you mean though, I'll keep the bug for now
