When studying, the learning count now indicates the number of
learning cards due within the learn ahead limit, instead of the total
number of learning steps required to complete that day.
Also fix the ineffective limit clauses in the learning counts.
- fetch reviews from all child decks at once, sorted by due order
- shuffle the gathered cards as we did previously
- review limits on child decks are ignored - only the current deck and
its parents control what the limit is
- to make the deck list consistent with actual counts, we can't sum the
child counts, as the sum in the parent limit>child limit case may not
reflect the actual number of cards that would be presented
the previous approach meant we weren't able to preserve the card state
exactly when cards were in learning, since we didn't record the step
position prior to cards being moved into the filtered deck.
it also meant the answer buttons needed to change depending on state - 4
for cards in learning/review, but 2 when the card is on the final step
or is a review.
instead, in preview mode cards always have 2 buttons: again will repeat
again after a delay, and good immediately removes the card and restores
it to its previous state.
to accomplish this, we use a separate queue #, as the learn count
always needs to have a 1:1 correspondence to the number of cards
Experiment with ignoring dirMod and scanning the folder for changes on
each sync. Use scandir() for better performance. Please let me know if
this causes a noticeable slowdown for you.
Users can now mark individual cards with one of four different coloured
flags, instead of relying on a tag that applied to the whole note.
- replaced marking functionality in reviewer and browser with new
flag options
- added flag:x search
- marked and leech tags now show in normal tag list in filter screen,
instead of being treated specially
- the other clients will need updating to set and shown the flags, but
flags set in the beta should be preserved by the other clients
