ipsi - looks like there's a bug in the duplicate-checking algorithm; it seems to be ignoring the traditional character ("althw") column when only a simplified headword is supplied, rather than checking to see if both it and the simplified character column match that headword. Easy to fix, anyway. The ABC superscripts etc are already stripped out when the entries are added to flashcards, so they don't factor in to the duplicate check - spaces and punctuation, however, do, at least for the moment. (skipping those is really really slow and would probably double how long imports take)
I don't know of any good way to check for the presence of background processes on Palm, so while we could include a note about pTunes etc in the manual there's not really any good way to put up an alert about it. Bringing back the option to mark a card correct/incorrect without revealing it would be tricky since the new flashcard system is somewhat more militant about making sure commands are actually appropriate for the current context - it'd need another preferences option, and at this point every time we add another preference an angel loses its wings. Could consider it in 2.1, though, since we'll probably have to add two or three more screens' worth of preferences anyway for that (I can already tell the reader's going to need at least one screen of its own for button / toolbar / etc customizations).
You're right about that count field, we forgot that All / repetition-spaced sessions might have more than three digits' worth of cards in them.
Fleminator - good point on including a dictionary name in duplicates, we should probably also include category information for the existing card. (and maybe even the new one too, though that's a bit harder) The free-answer matching system is still a bit glitchy like that, until recently it also shifted everything over by one when it ran into a capitalized Pinyin syllable. It is limited to 4 characters, and free-answer sessions automatically exclude any cards that are too long to fit. (accommodating more than 4 characters would require us to redesign the entire interface, which isn't even a possibility until 2.1)
I mentioned the cause of those resets a few pages ago - basically Palm OS handles a form exiting a completely different way depending on whether it's done deliberately by the user or forced by the operating system, and we haven't gotten around to testing every single dialog with the latter exit method yet. So for now you should pretty much always go back to the main dictionary screen before exiting - do you ever notice soft resets in that or do they seem to be confined to a few specific dialogs like Statistics? The user dictionary entry issue sounds like another bug, apparently it's still creating the entry even when the card is a duplicate - should be easy enough to fix anyway. Were you looking at the entry in the main dictionary screen or somewhere else (say the Edit Entry screen)?
The Settings button is there because it's not obvious that choosing Advanced from the top menu would let you change the sort order / display fields, something we imagine a lot of people would find useful. Really those should probably go on a separate screen, but since changing the sort order requires a whole new search anyway it seemed like combining them would be more efficient (saves you from waiting for two long searches instead of one). Adding a font size control would make that screen even more painfully cluttered than it is now, so that's a no-go - I guess we could use the font size setting from the regular dictionary entry list, but adding extra lines of text is going to make scrolling that list significantly slower so I don't know if it's really such a good idea when the scrolling is already borderline too-slow-to-be-usable.
There's a lot more we can do with flashcard field selection, the current score selection option was included mainly so that people who were already using that functionality in 1.0 could at least get the same thing in 2.0 - four fields may not be enough to encompass all of the different field settings we have now, but they should be enough to reproduce any of the headword/pron/defn combinations people were using with the old system at least. In 2.1 we might try for something more comprehensive which actually does switch between different test types (and could perhaps also test you on each card in several different ways, maybe even storing the results of those tests in different scorefiles depending on the test type) - obviously it's an area we can do a lot more with.
The Palm table system we use for category lists only supports empty and checked checkboxes, so getting them to display minus signs would require a pretty major rewrite - we probably should have those tables expand to display all checked categories on open, though. (along with checking all of the child categories if a parent category is selected, and unchecking the parent if any of its children aren't - again something that's very difficult on Palm, though) Looping incorrect answers at the end turned out to require almost no effort (the system was actually specifically checking to see whether it was already running through incorrect answers when it ran out of cards, and not running through them again if so, so all we had to do was turn off that check) so that's already been fixed now.
radioman - you should be able to change the font sizes in the Display tab under Advanced settings. (though a few people have suggested those aren't always saved correctly) Putting pinyin neatly below the headword is actually kind of tricky because a lot of headwords take up more than one line - in a case like
青出於
藍 qīngchūyúlán
versus
青出於
藍
qīngchūyúlán
the former actually ends up looking considerably tidier.
