gato - dragging handles to reorder items is the convention on iPhone, so in general I'm inclined to stick with that rather than rolling out our own interface. Tapping to change settings currently only works when you're not reordering dictionaries, though I suppose we might as well make it work all the time.
Eggwind - yeah, we do cram a lot of settings in there

We might eventually want to roll out some sort of alternate / simple / fewer-options-enabled settings interface, but at the moment we've got a lot of other areas of the UI we'd like to improve on too...
As far as the instruction manual, when the reader module isn't activated that tab is actually replaced by one that takes you directly to the manual, so at least for people not immediately transferring over their Palm/WM licenses it should be easier to find; if you have any ideas for where else we could put it, though (bearing in mind that we're saving the fifth tab bar slot for flashcards), let us know.
hairlyleprechaun - thanks!
estudiando - could you expand on this a bit? Would you want all (or some) Unihan details to be appended to the end of every single-character entry, or would you just want it to be offered as a normal dictionary that you can switch to?
