* Remove duplicate backend columns
* Remove duplicate column routines
* Move columns on frontend from state to model
* Generate available columns from Colum enum
* Add second column label for notes mode
I think this may have accidentally been changed in the refactoring.
If we discard self._rows, it will result in the entire table flashing
"..." until the new data is available. Instead, we leave the cached
rows alone, and just update the cutoff point, so we can serve stale
content (avoiding any visible redraw) until the new data is available.
I've updated search() to reset the rows there, so we free up memory
on a new search.
The backend knows exactly which op has executed, and it saves us having
to re-implement this logic on each client.
Fixes the browser table refreshing when toggling decks.
Instances can pass handled_by=self to more easily ignore events they
initiate.
Fixes ugly refresh when expanding/collapsing decks, but we're still
refreshing the card/notes area unnecessarily in that case.
Updating a deck via protobuf is now exposed on the backend, but not
currently on the frontend - I suspect we'll be better off writing
separate routines for the actions we need instead, and we get a better
undo description for free.
This is currently causing an ugly redraw in the browse screen, which
will need fixing.
- use strum to generate an iterator for the protobuf enum so we don't
forget to add new labels if extending in the future
- no add-ons appear to be using dynOrderLabels(), so it has been removed
@RumovZ perhaps a similar approach might work for listing the available
browser columns as well?
If the switch triggers heavy GUI action, like a lot of paint()s, the
concurrently running switch animation may look choppy.
A small timer makes these events execute first and the animation will
run smoothly afterwards when the event queue has been drained.
1) Check whether full row height is in viewport instead of just the
top left corner.
2) Add timer before scrolling to current row so editor will already
be set up.
