A few ideas born out of a recent flashcard session.
1) For the hardware buttons on my T5, if they are set for portrait operation, it would be useful to have those same buttons (including the center rocker switch button assignments) to remain intact. Maybe even rotate 90 degrees the assignment of the individual rocker sides. I believe currently, if I put a flash card session into landscape, the rocker hardware (and other HW switches?) are disabled. At a minimum, just to leave the HW buttons enabled in the exact same configuration would be preferable to me than to disable them.
2) During the display of definitions in flashcards, etc., there is an option to display which dictionary is being utilized in the definition. I am interested in an option that also allows me to see what categories are utilized by the card, without having to go to the info or category button. This would be basically an effort to simplify housekeeping during a session. Specifically, with a large number of cards, I find many can be miscategorized (typically with too many labels for a particular character), or for which I am unclear if a particular special category is assigned (e.g., "review this with teacher A"). Perhaps an x could also be added next to each category to allow the elimination of the category from a given card, similar to scheme for the elimination of labels in Gmail. I would also envision a prompt that says "are you sure you want to eliminate the category" before allowing the deletion.
EDIT - I now see some of the hardware buttons are functional in landscape mode, but the rocker functionality is only partially there.
