Adds browser columns for initial fail rate, card age, and average daily time spent, plus leech export and age/unique-day filtering tools for faster suspension.
Displays a post-review summary of cards reviewed, mistakes, and average time, then builds a redo deck of incorrect cards and offers mistake history, leech coaching, and shareable study summaries.
Provides leech and lapse management tools including markers, reversal, custom automated actions, cross-device sync, browser options, reviewer shortcuts, and text macros.
Detects cards trending toward leech status when you press Again, checks their review history, and shows a short tooltip or popup urging you to pause and relearn without altering scheduling.
Finds notes tagged leech that have no suspended cards and lists them in the Browse window, where they can be untagged or otherwise handled.
Adds configurable Apple Fitness-style progress ring widgets to Anki dashboards, tracking tags, decks, custom searches, or daily study progress, with visual editing and click-through to the Browser.
This add-ons aims to offer new ways to understand how your card might not be leeches, based on more criteria than simply looking at lapses count

Added new field to see the Leech status of a card and the key metrics allowing to determine if it's a leech or not.
leeches:allleeches:activeleeches:recoveringleeches:recoveredleeches:healthyThose flags combines as "OR", meaning the result will be all results merged.
You can also specify custom leech detection threshold, those are valid searches :
leeches:active[drop_count=5,drop_ratio=.5]leeches:active[drop_count=5]leeches:active[drop_ratio=.5]leeches:recovered[drop_count=1,drop_ratio=.5] leeches:active[drop_count=5,drop_ratio=.5]Note :
*, and then only the search is filtered. So,
(A leeches:active) OR (B leeches:recovered) will be equal to
(A *) OR (B *) AND (leeches:active OR leeches:recovered.
If you want proper evaluation of such queries, you should populate a card field with the leech status and filter on it
like you would do with any normal card fields.leeches:active[drop_count=1] leeches:active[drop_count=2] the drop_count=2 will replace the drop_count=1leeches:* filters are also supported in Stats screens and plugins doing card searches (for example Search Stats Extended).
