I have just released Tanglet 1.1.0. The two biggest features are the addition of several more timer modes, and the option of playing on a larger board. Some of the smaller changes include an option to see the maximum score (either during gameplay, or at the end of play), and an option to hide the missed words list.
I also tweaked the interface slightly. I added an outline to the text in the timer to make it easier to read. I also tweaked it so that the text highlight changes from a light blue to a darker blue when a word is long enough to be guessed.
