Anki add-on for displaying notes which are tagged "leech" but have no suspended cards

https://ankiweb.net/shared/info/805244924

Description

Cards which are answered incorrectly too many times become leeches. When this happens, the note associated with the card receives a "leech" tag, and by default the card is suspended. (Note that Anki lets you configure the Leech Threshold and Leech Action in each deck's Options)

When manually unsuspending a card, it is easy to forget to remove the "leech" tag from the note. It is also cumbersome to check manually for the rare cases where a "leech"-tagged note actually has more than one suspended card.

This add-on finds notes which are tagged "leech" but have no suspended cards, and displays them in the Browse window. You can then choose to untag them or take any other action.

How it could be done manually instead

Without this add-on, you could perform the same function manually by doing the following:

• Switch to Notes mode in the Browse window.
• Search for is:suspended
• Click on the first line of results, and then select all lines. (In Windows this can be done with Ctrl-A, or by scrolling down to the final line of results and holding Shift while clicking on it).
• Do "Add Tags..." and apply a tag like "is_suspended" or any other newly invented tag name of your choice.
• Search for tag:leech -tag:is_suspended to get the desired list.
• Clean up afterward by deleting the "is_suspended" tag.
