This module is a Configuration Kit that provides a system for managing user-specific tasks. On first install the system is simple by design, but the tasks are stored as Storage Entities so you're free to modify and add fields as needed to suit the specific needs of your site: due dates, ticket IDs, a "task type" taxonomy reference, and so on.
The module also includes a submodule meant to provide improved formatting when using Tasks with the Olivero theme. If not using Olivero, you may want to copy some or all of the submodule's CSS into you own theme, and modify it as you see fit.
After being "checked" as done, a task will still display, until the next time the page is refreshed. If you would prefer to have such tasks disappear as soon as they're checked, install the Views Flag Refresh module and update the view configuration to use it.
