Updating Kiku
Download the latest Kiku_v*.apkg from the Release page.
Before importing the .apkg, you need to delete all existing Kiku files.
This is required because Anki will not overwrite files that already exist.
You may keep _kiku_config.json and _kiku_plugin.js.
After that, import the .apkg into Anki as usual.
INFO
If you choose to keep _kiku_config.json, make sure to open the settings page and click Save after updating it. This ensures that the settings in the Front/Back/Styling templates are synced with your configuration.
