The Rewarder plugin enhances task completion in Obsidian by introducing a reward system. Users can create a list of rewards in a specified file, with options to set occurrence rates, inventories, and associated images for each reward. When a task is completed, the plugin randomly selects a reward based on defined criteria, notifying the user via popup or notice. Rewards can also be recorded in daily notes. The plugin allows extensive customization, including renaming occurrence levels, defining inventory limits, and linking images. Additional features include tracking completed tasks in daily notes and an alternative mode for displaying quotes instead of rewards.
