The コミケwebカタログ追加メモ is a useful extension for the コミックマーケットwebカタログ, a website that provides information about the Comiket event. With this extension, users can conveniently use the memo feature on the web catalog site.

Users can make notes about the circles they purchased from in previous Comiket events, as well as circles they didn't particularly enjoy. The extension allows users to leave free-form notes, providing a way to keep track of their experiences and preferences.

The コミケwebカタログ追加メモ extension was released in August 2015, coinciding with the summer Comiket event. The latest version, v2.1, introduced the ability to use the Ctrl+s shortcut to apply changes and implemented a scrolling feature to prevent layout issues with long descriptions of circles.
