Maintenance: Note Type usage in Decks addon lets you keep track of the usage of specific “Note Types” (also called “models”) by notes in specific decks.
Purpose and usage
This addon can help you to verify what Note Types are used in your decks where the built-in Note Type editor shows only aggregated (per-Note Type) information. That may come in handy if you maintain a non-trivial collection, with some non-default Note Types. Perhaps some Note Types you’ve created yourself but some might have been imported along with shared decks. Some might have gotten “strange names” (like “Basic-4bef4”) in the process…
Especially if you’re a shared deck maintainer you may need to verify whether all your public notes use Note Types you want them to.
Maintenance: Note Type usage in Decks can show you the data in simple tablular form or as “pivot table” - with decks and Note Types as rows or columns and number of notes (and/or cards) on crossings.
Data shown in the table can be exported to text files recognized by tools like Excel or LibreOffice Calc (Tab-separated, UTF-16 unicode files). That’s the preferred way of analysing “pivoted” data as column names tend to be long there and Qt library hasn’t got vertical column names built-in (see screenshots below).
Support
Addon was tested the addon on Windows (7) and Linux (Ubuntu 17.04 64bit) but it should work on other platforms too.
Addon source will be made available github soon.
