The Checkbox Sounds plugin adds an auditory cue when a checkbox is ticked off in Obsidian. This simple enhancement allows users to hear a completion sound each time they mark a task as done. The plugin offers customization options, allowing users to change the sound used for the completion cue through the plugin's settings. This small but impactful feature can improve the user experience by providing immediate audio feedback during task management. Future updates may include more sound options, the ability to add custom sounds, and the option to play a random sound each time.
