The default 1 rem is fine, but we need to apply the default font size
to the html element instead of the body for the definition of rem to
update.
Fixes#1174
Also:
- fix issues where the Undo action in the Browse screen was not
consistent with the main window. The existing hook signature has been
changed; from a snapshot of the add-on code from a few months ago, it
was not a hook that was being used by anyone.
- change the undo shortcut in the Browse window to match the main
window. It was different because undoing a change in the editing area
could accidentally trigger an undo of an operation, but the damage is
limited now that (most) operations can be redone. If it still proves to
be a problem, perhaps we should just always swallow ctrl+z when an
editing field is focused.
The previous behaviour when a non-sortable column was clicked was to
trigger the sorting routine, which was usually a no-op, but would
reorder rows if the configured sort column was hidden.
Instead of using a separate undo queue, the code now defers checking for
newly-due learning cards until the answering stage, and logs the updated
cutoff time as an undoable change, so that any newly-due learning cards
won't appear instead of a new/review card that was just undone.
Queue redo now uses a similar approach to undo, instead of rebuilding the
queues.
Avoids duplicate work, and is a step towards allowing the next
states to be modified by third-party code.
Also:
- fixed incorrect underlined count, due to reviews being labeled as
learning cards
- fixed reviewer not refreshing when undoing a test review, by splitting
up backend queue rebuilding from frontend reviewer refresh
- moved answering into a CollectionOp
- backend now updates current notetype as part of addition
- frontend no longer implicitly adds, so we can assign a new name and
add in a single operation
- The old options are still available with a shift+click
- Translations still need updating
- See b7747b6a38 for some examples
of extending the screen in an add-on
